[jira] [Commented] (MAPREDUCE-4659) Confusing output when running
"hadoop version" from one hadoop installation when HADOOP_HOME points to
another
[ https://issues.apache.org/jira/browse/MAPREDUCE-4659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13456301#comment-13456301 ]
Harsh J commented on MAPREDUCE-4659:
------------------------------------
Good idea, I've seen this bite a few users before. Note though, that on 2.x and current 1.x, the HADOOP_HOME was deprecated for HADOOP_PREFIX and per-component homes. So maybe we could also look at HADOOP_COMMON_HOME, which is the lib set that has the VersionInfo?

> Hadoop version X is downloaded to ~/hadoop-x, and Hadoop version Y is downloaded to ~/hadoop-y. HADOOP_HOME is set to hadoop-x. A user running hadoop-y/bin/hadoop might expect to be running the hadoop-y jars, but, because of HADOOP_HOME, will actually be running hadoop-x jars.
> "hadoop version" could help clear this up a little by reporting the current HADOOP_HOME.
