[jira] [Updated] (HBASE-19004) master.RegionStates: THIS SHOULD NOT
HAPPEN: unexpected
[ https://issues.apache.org/jira/browse/HBASE-19004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
lujie updated HBASE-19004:
--------------------------
Description:
When I send stop regionserver command, A log entry in master make me confused: THIS SHOULD NOT HAPPEN: unexpected. I check the code,find the log printed in default condition(eg: if() {} else if() {} else{log.warn()}). I think this condition should be handled
