Subject [jira] [Commented] (HADOOP-7894) bin and sbin commands don't use JAVA_HOME when run from the tarball
Date Fri, 11 Jan 2013 06:00:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13550864#comment-13550864

Eli Reisman commented on HADOOP-7894:
-------------------------------------

You know, I did, and it didn't pick up. I also tried the env_keep sudoers fix mentioned in
another thread, etc. and no dice. In the end (running ubuntu) I had to hardcode the JAVA_HOME
and a few other env vars into the env scripts in the run scripts in order to get my 2.0.2-alpha
YARN, HDFS, and MR all running successfully. I'm on the wrong machine but if you're curious
let me know and I can post a more detailed idea of what ended up working, if it helps diagnose
the problem. Its certainly not ideal, but it is getting me by for now. Thanks for the advice!
