----------------------------------
Summary: RS should abort if OOM in Reader thread
Key: HBASE-21357
URL: https://issues.apache.org/jira/browse/HBASE-21357
Project: HBase
Issue Type: Bug
Affects Versions: 1.4.8
Reporter: Allan Yang
Assignee: Allan Yang
It is a bit strange, we will abort the RS if OOM in Listener thread, Responder
thread and in CallRunner thread, only not in Reader thread...
We should abort RS if OOM happens in Reader thread, too. If not, the reader
thread exists because of OOM, and the selector closes. Later connection select
to this reader will be ignored

Leaving the client (or Master and other RS)'s call wait until SocketTimeout.
