Anoop Sam John commented on HBASE-11584:
----------------------------------------
In Step#4, instead of removing these configs, can you make this way and check
once?
{code}
<property>
<name>hbase.regionserver.hlog.reader.impl</name>
<value>org.apache.hadoop.hbase.regionserver.wal.SecureProtobufLogReader</value>
</property>
<property>
<name>hbase.regionserver.hlog.writer.impl</name>
<value>org.apache.hadoop.hbase.regionserver.wal.SecureProtobufLogWriter</value>
</property>
<property>
<name>hbase.regionserver.wal.encryption</name>
<value>false</value>
</property>
{code}
Still WAL encryption will be disabled for new writes.

> Key: HBASE-11584
> URL: https://issues.apache.org/jira/browse/HBASE-11584
> Project: HBase
> Issue Type: Bug
> Components: hbck, HFile
> Affects Versions: 0.98.3
> Environment: SuSE 11 SP3
> Reporter: shankarlingayya
> Priority: Critical
>
> HBase file encryption some consistences observed and data loss happens after
> running the hbck tool,
> the operation steps are as below.
> Procedure:
> 1. Start the Hbase services (HMaster & region Server)
> 2. Enable HFile encryption and WAL file encryption as below, and perform
> 'table4-0' put operations (100 records added)
