[jira] [Created] (MAPREDUCE-4659) Confusing output when running
"hadoop version" from one hadoop installation when HADOOP_HOME points to
another
Sandy Ryza created MAPREDUCE-4659:
-------------------------------------
Summary: Confusing output when running "hadoop version" from one hadoop installation when HADOOP_HOME points to another
Key: MAPREDUCE-4659
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4659
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client
Affects Versions: 2.0.1-alpha
Reporter: Sandy Ryza
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.

Todd Lipcon commented on MAPREDUCE-4659:
----------------------------------------
Or perhaps just print the path to the hadoop common jar itself? That way this works even for projects like HBase that depend on Hadoop and print the hadoop version info in their webpage. It's also more independent of packaging, etc.

What would be the best way to find the path to the hadoop common jar? The script currently adds all the jars in certain folders.

------------------------------------
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?

-----------------------------------------------
Instead duplicating the code for findContainingJar() we should create a util class (annotated as private) and used from JobConf.java & VersionInfo.java.
