HBase coprocessor not updating after redeploy

Question

I\'m using HBase 1.1.2, and trying to redeploy a custom endpoint coprocessor to fix an error in my Java code. I made some changes to the coprocessor code and redeployed it via t

Answer 1

you need to restart hbase server.

cd $HBASE_HOME/bin
$sh stop-hbase.sh
$sh start-hbase.sh

you cann't change coprocessor jar file when hbase is running. so you should restart hbase server after your step 6.

Answer 2

Restarting HBase did the trick; the jar in /tmp/hbase-hbase/local/jars/tmp/ was removed, and my next deploy was successful.

This is a bug in HBase, either in the documentation or the code. I'll raise a ticket with the HBase Jira.
