[jira] [Created] (HBASE-7871) HBase can be stuck in the shutdown
nkeywal created HBASE-7871:
------------------------------
Summary: HBase can be stuck in the shutdown
Key: HBASE-7871
URL: https://issues.apache.org/jira/browse/HBASE-7871
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.96.0
Reporter: nkeywal
Attachments: TestStartStop.java
