-----------------------------------
Summary: Add exception handler for lease thread
Key: HBASE-13988
URL: https://issues.apache.org/jira/browse/HBASE-13988
Project: HBase
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Liu Shaohui
Assignee: Liu Shaohui
Priority: Minor
In a prod cluster, a region server exited for some important
threads were not alive. After excluding other threads from the log, we doubted
the lease thread was the root.
So we need to add an exception handler to the lease thread to debug why it
exited in future.
