------------------------------
Summary: Rewrite deadlock prevention due to concurrent connection
close
Key: HBASE-14449
URL: https://issues.apache.org/jira/browse/HBASE-14449
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
The deadlock prevention approach used in HBASE-14241 introduces unnecessary
logic which is not intuitive.
Depending on the value for config hbase.ipc.client.specificThreadForWriting ,
there may or may not be CallSender threads running.
The attached patch simplifies deadlock prevention by using a Set which
represents the Connections to be closed. Outside the synchronized (connections)
block, this Set is iterated where the Connections are closed.
