title: HBase coprocessor remote debugging
body: <p>How to remote debug HBase coprocessor - RegionObserver?</p>
  
  <p>I'm using Cloudera Quickstart.</p>
  
  <p>There is a <a href="http://mail-archives.apache.org/mod_mbox/hbase-user/201408.mbox/%3CCANZa=GsVox=N7YYsEe32LcVEnWs8_KweLYad-BTRnzF91zTkLg@mail.gmail.com%3E" rel="nofollow noreferrer">question</a> about it, but there is no information about where to put that <code>exec</code> command.</p>
  
  <p>Also I tried <a href="https://my.oschina.net/pangzhuzhu/blog/327120" rel="nofollow noreferrer">this instructions</a>, but HBase doesn't start with that.</p>
  
  <p>So what is the right way to remote debug coprocessors?</p>
