-----------------------------------------

             Summary: 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.
