--------------------------
    Release Note: 
Now the default WALProvider is AsyncFSWALProvider, i.e. 'asyncfs'.
If you want to change back to use FSHLog, please add this in hbase-site.xml
{code}
<property>
<name>hbase.wal.provider</name>
<value>filesystem</value>
</property>
{code}
If you want to use FSHLog with multiwal, please add this in hbase-site.xml
{code}
<property>
<name>hbase.wal.regiongrouping.delegate.provider</name>
<value>filesystem</value>
</property>
{code}

Requires Hadoop-2.8.0 at least. Depends on PBHelperClient added here:
