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.
