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.
> Sqoop2: Create debugging web interface for Sqoop 2
> --------------------------------------------------
>
> Key: SQOOP-2766
> URL: https://issues.apache.org/jira/browse/SQOOP-2766
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.99.7
> Reporter: Jarek Jarcec Cecho
> Fix For: 1.99.7
>
>
> 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.
