Hi All.
I am using 0.98.6 HBase.
I observed that when I have the following value set in my hbase-site.xml file
<property>
<name>hbase.regionserver.wal.encryption</name>
<value>false</value>
</property>
<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>
And while log splitting on hbase service restart, master shutdown with
following exception.
Exception in master log

Question,
When wal encryption is disabled should we set SecureWALCellCodec for
cellCodecClsName in WALHeader.Builder object ?
