Subject [jira] [Commented] (HADOOP-12366) expose calculated paths

Varun Vasudev commented on HADOOP-12366:
----------------------------------------

Thanks for the patch [~aw]!

Couple of things -
1) The patch doesn't apply cleanly to trunk any more. I see issues with 'hdfs'.
2.) Some of the variables printed out(such as JAVA_HOME, HADOOP_COMMON_HOME and HADOOP_CONF_DIR)
have absolute paths while some(such as HADOOP_COMMON_DIR, HADOOP_COMMON_LIB_JARS_DIR and HADOOP_COMMON_LIB_NATIVE_DIR)
have relative paths. Do you think the difference matters or do we expect users to know what
the individual variables are referring to?

The rest of the patch looks good.

> It would be useful for 3rd party apps to know the locations of things when hadoop is
running without explicit path env vars set.
