Release Note:

Hide
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}

This patch also sets hbase.wal.async.use-shared-event-loop to false so WAL has its own netty event group.

As it should be predicated on passing basic cluster ITBLL
