[jira] [Commented] (SQOOP-2766) Sqoop2: Create debugging web interface for Sqoop 2

["Colin Ma (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SQOOP-2766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15082313#comment-15082313 ] 

Colin Ma commented on SQOOP-2766:
---------------------------------

[~jarcec], this should be an useful feature for Sqoop.
For thread dump, it can be implemented as the Hadoop.
For metrics, maybe the following information can be collected, eg:
    link             10   (enabled 5, disabled 5)
    connector   ..........................
    job              10 (running 3, success 6, failed 1)
I'll take this, and feel free for any comments.

> Most of the Hadoop components have a special web interface (read "running on different port") where admins can show various useful debugging information such as:
> * Thread dump (pretty much output of {{jstack}} command) ([mentioned even in Hadoop book|https://books.google.com/books?id=MhqkBwAAQBAJ&pg=PA331&lpg=PA331&dq=hadoop+thread+dump&source=bl&ots=VzKJP2bUXg&sig=5AfZ-Y0GGSoDIZuRqbXf028OVGs&hl=en&sa=X&ved=0ahUKEwjax9fC84PKAhUW9mMKHZF2DHYQ6AEIJTAB#v=onepage&q=hadoop%20thread%20dump&f=false])
> * Metrics
> * And many many more
> We currently don't have any metrics or much to explore, but I've already been in situation where getting jstack easily would be super helpful and hence it would be great to create such interface.
