All of this information is stored in a MySQL database with near-realtime access.įor more sophisticated diagnoses, Cloudera Manager now has a snapshotting feature that can do a core dump on the system state of nodes in the cluster on a scale of minutes to an hour and captures versions of systems and software stacks, settings, logs, any changes, and such that are occurring on the system and packages all this data up and pops it into a file and sends it off to a sysadmin or Cloudera to do debugging and tuning.

The Hadoop control freak can also send alerts to cluster managers when nodes or services are running slowly or starting to fail this alerting system has hooks into popular IT management frameworks for consolidating alerts to sysadmins.Ĭloud Manager also has a feature called global time control, which correlates logs, system changes, configuration, running jobs, and other aspects of the Hadoop cluster to help admins figure out what went wrong when it inevitably does (as is the case with all complex systems).

But those engaging in open core distribution also peddle closed source add-ons for the open source tools usually under a perpetual or subscription license with an annual support contract and usually offering finer-grained management, more scalability, connectors to third party products, and such.Ĭloudera Manager can gather and scan Hadoop logs from the servers in the cluster to look for weird stuff and can even do proactive checking for HDFS and its increasingly popular column-oriented database overlay, HBase.

That means it wraps up the key open source elements of a particular project – in this case the Hadoop MapReduce application, its underlying Hadoop Distributed File System (HDFS), and a bunch of other things – and distributes this for free and offers commercial-grade support for the stack. Like other open source companies founded in recent years, Cloudera embraces an "open core" distribution model. Cloudera thinks it has an edge in managing Hadoop clusters, and believes further that it will extend its lead with a new control freak for its Hadoop distro, called, appropriately enough, Cloudera Manager.

That's because the underlying Hadoop data muncher is an open source project, so any company that wants to make money on the big data wave has to add value above and beyond the core Hadoop stack. Updated Cloudera might have been the first company to try becoming the Red Hat for stuffed elephants, but with MapR, Hortonworks, IBM, Oracle, DataStax, and EMC all trying to commercialize Hadoop, Cloudera has to keep on its toes and perhaps even balance on a ball.
