Subject [jira] [Commented] (HADOOP-8938) add option to do better diags of startup configuration
Date Wed, 17 Oct 2012 10:52:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477778#comment-13477778

Steve Loughran commented on HADOOP-8938:

Things that are often useful to know
* Java home: value and what is at the far end
* Hadoop conf directory picked up (symlink games can cause confusion)
* which *-site.xml files are being picked up (full path)
* full path to commands
* native lib directory and contents

This isn't stuff that needs to be printed every run, so it should be something that could
be turned on if needed.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-8938
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: bin
>    Affects Versions: 1.1.0, 2.0.2-alpha
>            Reporter: Steve Loughran
>            Priority: Minor
> HADOOP-8931 shows a symptom of a larger problem: we need better diagnostics of what all
the environment variables and settings going through the hadoop scripts to find out why something
isn't working. 
> Ideally some command line parameter to the scripts (or even: a new environment variable)
could trigger more display of critical parameters.
