Subject [jira] [Created] (HBASE-14811) HBaseInterClusterReplicationEndpoint retry logic is broken

-------------------------------------

             Summary: HBaseInterClusterReplicationEndpoint retry logic is broken
                 Key: HBASE-14811
                 URL: https://issues.apache.org/jira/browse/HBASE-14811
             Project: HBase
          Issue Type: Bug
          Components: Replication
    Affects Versions: 2.0.0, 1.2.0, 1.2.1
            Reporter: Ashu Pachauri
            Assignee: Ashu Pachauri


In HBaseInterClusterReplicationEndpoint, we do something like this:
{code}
entryLists.remove(f.get());
{code}

where f.get() returns an ordinal number which represents the index of the element in the entryLists
that just succeeded replicating. We remove these entries because we want to retry with remaining
elements in the list in case of a failure. Since entryLists is an ArrayList, the subsequent
elements are shifted left in case we remove an element. This breaks the intended functionality.
The fix is to reverse sort the ordinals and then perform the deletion in one go.
