[jira] [Commented] (HBASE-18377) Error handling for
FileNotFoundException should consider RemoteException in
ReplicationSource#openReader()
[ https://issues.apache.org/jira/browse/HBASE-18377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16085908#comment-16085908 ]
Ted Yu commented on HBASE-18377:
--------------------------------
Patch for branch-1.3 refactors handling for FNFE. For FNFE wrapped in RemoteException, the same handling is applied.
