MapR unleashes two 'next-generation' Hadoop distros

Well, one next-generation, and one free semi-next


MapR Technologies – a Silicon Valley startup that spent the last two years revamping Hadoop for use in the enterprise – has unveiled two new ditributions of the distributed number-crunching platform.

On Wednesday, amidst Yahoo!'s annual Hadoop Summit in Santa Clara, California, MapR announced a free offering known as the Map3 M3 Edition and a for-pay version known as MapR M5. Both are based on the open source Apache Hadoop project, but MapR has rebuilt certain portions of the platform in an effort make Hadoop both more nimble and more reliable. The company likes to say it has delivered the "next generation of Hadoop".

The free M3 distro can be used on an unlimited number of nodes, but it lacks the certain Hadoop enhancements available with the M5 edition, which can be licensed for $4,000 per node per year. These are the first Hadoop products directly available from MapR. Previously, the company announced that its technology will underpin the upcoming Hadoop offerings from EMC.

Though MapR refers to its two new products as "distributions", these are not entirely open source. MapR has made extensive changes to the underlying platform that are proprietary. That said, the company recently signed a Corporate Contributor License Agreement with the Apache Foundation, signaling its intention to contribute code back to the community, and vice president of marketing Jack Norris tells The Register that such work is already underway. "It's an evolving process," he says.

Unlike Apache Hadoop, both MapR distros can be mounted on a standard network file system (NFS). "What we've done is rearchitect the storage services so that they provide random read and random write for multiple readers and writers, and then we expose that as an NFS mount, so in addition to being able to use that data from Hadoop APIs, you can use all your standard Linux tools and Unix tools and applications," MapR CEO and cofounder John Schroeder has told us. "You can create real-time data streaming out of Hadoop. You can make Hadoop look like a big C: drive on your Windows desktop."

Both distros also include the MapR "Heatmap", a graphical interface for managing Hadoop nodes. The company claims that both products provide much higher performance than the open source incarnation of Hadoop. And in addition offering the core Hadoop File System (HDFS) and Hadoop MapReduce platforms, both products include sister platforms such a HBase (a distributed database), Hive (a query language), and Zookeeper (a means of managing distributed services). There are all existing open source platforms, but according to Norris, MapR has "pre-tested" all these Hadoop pieces in concert.

Though the free M3 distro can be used on an unlimited number of nodes, it does not include the new Hadoop job tracker and name space built by MapR. These are only available with the for-pay M5 edition.

Typically, the Hadoop Job Tracker – which distributes jobs across a cluster and manages their execution – is a single process running on a single machine. With the M5 edition, MapR has introduced a Job Tracker that's distributed across several machines. With Apache Hadoop, the global namespace is also a single point of failure, and the MadR distributes this NameNode as well.

The MapR M5 edition also includes what the company calls 24-by-7 support. ®

    Imagine a future where racks of computer servers hum quietly in darkness below the surface of the Moon.

    Here is where some of the most important data is stored, to be left untouched for as long as can be. The idea sounds like something from science-fiction, but one startup that recently emerged from stealth is trying to turn it into a reality. Lonestar Data Holdings has a unique mission unlike any other cloud provider: to build datacenters on the Moon backing up the world's data.

    "It's inconceivable to me that we are keeping our most precious assets, our knowledge and our data, on Earth, where we're setting off bombs and burning things," Christopher Stott, founder and CEO of Lonestar, told The Register. "We need to put our assets in place off our planet, where we can keep it safe."

    In brief The notorious Russian-aligned Conti ransomware gang has upped the ante in its attack against Costa Rica, threatening to overthrow the government if it doesn't pay a $20 million ransom. 

    Costa Rican president Rodrigo Chaves said that the country is effectively at war with the gang, who in April infiltrated the government's computer systems, gaining a foothold in 27 agencies at various government levels. The US State Department has offered a $15 million reward leading to the capture of Conti's leaders, who it said have made more than $150 million from 1,000+ victims.

    Conti claimed this week that it has insiders in the Costa Rican government, the AP reported, warning that "We are determined to overthrow the government by means of a cyber attack, we have already shown you all the strength and power, you have introduced an emergency."

    In a technical analysis, the researchers detail the various malicious stages and payloads of the campaign that used sanctions-related phishing emails to attack Russian entities, which are part of the state-owned defense conglomerate Rostec Corporation.

    The US Federal Trade Commission on Thursday said it intends to take action against educational technology companies that unlawfully collect data from children using online educational services.

    In a policy statement, the agency said, "Children should not have to needlessly hand over their data and forfeit their privacy in order to do their schoolwork or participate in remote learning, especially given the wide and increasing adoption of ed tech tools."

    The agency says it will scrutinize educational service providers to ensure that they are meeting their legal obligations under COPPA, the Children's Online Privacy Protection Act.

  • Mysterious firm seeks to buy majority stake in Arm China
    Chinese joint venture's ousted CEO tries to hang on - who will get control?

    The saga surrounding Arm's joint venture in China just took another intriguing turn: a mysterious firm named Lotcap Group claims it has signed a letter of intent to buy a 51 percent stake in Arm China from existing investors in the country.

    In a Chinese-language press release posted Wednesday, Lotcap said it has formed a subsidiary, Lotcap Fund, to buy a majority stake in the joint venture. However, reporting by one newspaper suggested that the investment firm still needs the approval of one significant investor to gain 51 percent control of Arm China.

    The development comes a couple of weeks after Arm China said that its former CEO, Allen Wu, was refusing once again to step down from his position, despite the company's board voting in late April to replace Wu with two co-chief executives. SoftBank Group, which owns 49 percent of the Chinese venture, has been trying to unentangle Arm China from Wu as the Japanese tech investment giant plans for an initial public offering of the British parent company.

  • SmartNICs power the cloud, are enterprise datacenters next?
    High pricing, lack of software make smartNICs a tough sell, despite offload potential

    SmartNICs have the potential to accelerate enterprise workloads, but don't expect to see them bring hyperscale-class efficiency to most datacenters anytime soon, ZK Research's Zeus Kerravala told The Register.

    SmartNICs are widely deployed in cloud and hyperscale datacenters as a means to offload input/output (I/O) intensive network, security, and storage operations from the CPU, freeing it up to run revenue generating tenant workloads. Some more advanced chips even offload the hypervisor to further separate the infrastructure management layer from the rest of the server.

    Despite relative success in the cloud and a flurry of innovation from the still-limited vendor SmartNIC ecosystem, including Mellanox (Nvidia), Intel, Marvell, and Xilinx (AMD), Kerravala argues that the use cases for enterprise datacenters are unlikely to resemble those of the major hyperscalers, at least in the near term.
