------------------------------
Summary: Error handling for FileNotFoundException should consider
RemoteException in ReplicationSource#openReader()
Key: HBASE-18377
URL: https://issues.apache.org/jira/browse/HBASE-18377
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
In region server log, I observed the following:
{code}
org.apache.hadoop.ipc.RemoteException(java.io.FileNotFoundException): File does
not exist: /apps/hbase/data/WALs/lx.p.com,16020,1497300923131/497300923131.

We have code in ReplicationSource#openReader() which is supposed to handle
FileNotFoundException but RemoteException wrapping FileNotFoundException was
missed.
