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.
