> 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.
