> Key: HBASE-15983
> URL: https://issues.apache.org/jira/browse/HBASE-15983
> Project: HBase
> Issue Type: Bug
> Components: Replication
> Affects Versions: 0.98.0, 1.0.0, 1.1.0, 1.2.0
> Reporter: Sean Busbey
> Assignee: Sean Busbey
> Priority: Critical
> Fix For: 2.0.0, 1.4.0, 1.3.1, 0.98.23, 1.2.5, 1.1.9
>
>
> In some particular deployments, the Replication code believes it has
> reached EOF for a WAL prior to successfully parsing all bytes known to
> exist in a cleanly closed file.
> The underlying issue is that several different underlying problems with a WAL reader are all treated as end-of-file by the code in ReplicationSource that decides if a given WAL is completed or needs to be retried.
