> Key: HBASE-5745
> URL: https://issues.apache.org/jira/browse/HBASE-5745
> Project: HBase
> Issue Type: Bug
> Components: wal
> Affects Versions: 0.95.2
> Reporter: Uma Maheswara Rao G
> Priority: Critical
>
> This is actually a kind of integration bug from Hbase perspective.
> Currently HDFS will count the partial block length as 0, if there are no
> locations found for the partial block. This can happend opn DFS restart,
> before DNs completely reports to NN.
> Explained the scenario in HDFS-3222. Actually this is a bug in HDFS. we may
> solve this in latest versions.
> So, whatever the versions Hbase using may have this bug. HMaster may not be
> able to replay the complete edits if there is an Hmaster switch also at the
> same time.
