[jira] [Commented] (HDFS-6468) Updating hadoop-daemon.sh to work as expected when nfs is started as a privileged user.

["Aaron T. Myers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-6468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14012637#comment-14012637 ] 

Aaron T. Myers commented on HDFS-6468:
--------------------------------------

Patch looks good to me, Mani. One question - can you please comment what testing of this patch you've done? I don't think our automated tests will actually exercise this change at all.

+1 pending Jenkins and an answer to the above question.

Also, no need to change it now, but for future reference we typically name the patch files just "<JIRA NUMBER>.patch", so "HDFS-6468.patch" in this case.

> When NFS is started as a privileged user, this change sets up required environment variables:
> HADOOP_PID_DIR = $HADOOP_PRIVILEGED_NFS_PID_DIR
> HADOOP_LOG_DIR = $HADOOP_PRIVILEGED_NFS_LOG_DIR
> HADOOP_IDENT_STRING = $HADOOP_PRIVILEGED_NFS_USER
> Also, along with the above, we also now collect ulimits for the right user.
