Master shuts down during log splitting on restart
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
2014-09-24 17:14:28,590 FATAL [master:host-10-18-40-18:60000] master.HMaster: Master server abort: loaded coprocessors are: [org.apache.hadoop.hbase.security.access.AccessController]

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