Description

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:

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

This file is still moved to oldWALs even though splitting failed.

Setting 'hbase.regionserver.wal.encryption' to false allows data recovery.
