Hi Guys, I am investigating a customized JMX agent fix based on coprocessor for hbase-10289. ---coprocessor makes the fix pluggable so user can switch to official JDK7 fix in future easily.
but I find with the fix the hbase fails to be stopped, because the tcp port is not closed ---the coprocessor stop method is never invoked. checking the code, it looks we miss the stop method? and the coprocessor examples code in hbase source tree ALL use empty stop method...so it would be a problem if coprocessor allocate OS resources such as file handle, tcp port? I verified adding the stop method invocation fixes the issue. can you please let me know if jira is needed? thanks. Qiang
