Date Sat, 26 Jul 2014 18:06:38 GMT

Andrew Purtell commented on HBASE-11595:
----------------------------------------

Tried the above procedure a few times. Not able to reproduce. Replied to the reporter on user@hbase
with a request to run through the above and provide more information.

>          Issue Type: Bug
>    Affects Versions: 0.98.3
>            Reporter: Andrew Purtell
>            Priority: Critical
>             Fix For: 0.99.0, 0.98.5, 2.0.0

> Reported using HBase 0.98.3 and HDFS 2.4.1
> All data before failure has not yet been flushed so only exists in the WAL files. During
distributed splitting, the WAL has either not been written out and synced in the same way
as an unencrypted WAL or is unreadable:
> {noformat}
> 2014-07-26 19:29:16,160 ERROR [RS_LOG_REPLAY_OPS-host1:60020-0] codec.BaseDecoder: Partial
cell read caused by EOF: java.io.IOException: Premature EOF from inputStream
> {noformat}
> This file is still moved to oldWALs even though splitting failed. 
> Setting 'hbase.regionserver.wal.encryption' to false allows data recovery.
