how to find hadoop distribution and version
My Hadoop run on Ubuntu and when I type "hadoop version" in console it shows below:
Hadoop 2.4.0Subversion http://svn.apache.org/repos/asf/hadoop/common -r 1583262Compiled by jenkins on 2014-03-31T08:29ZCompiled with protoc 2.5.0From source with checksum 375b2832a6641759c6eaf6e3e998147This command was run using /usr/local/hadoop/share/hadoop/common/hadoop-common-2.4.0.jar
For version details you can visit namenode-ip:50070 and look for Version: it will give you the Hadoop version
Note the First three numbers are Hadoop version In my case values is
2.5.0-cdh5.3.0, f19097cda2536da1df41ff6713556c8f7284174d So hadoop version is 2.5.0 and distribution is CDH whose version is 5.3.0
