Subject Re: RegionServer 60030 Show All RPC Handler Task is empty
Date Wed, 08 Jul 2015 09:32:15 GMT
Hi esteban,

For the dump url get the following out:


Tasks:
===========================================================


Executors:


For the json format, got the following output:

Shell > curl http://xxxx:60030/rs-status\?format\=json\&filter\=handler

[]


All output is empty
