Anoop Sam John commented on HBASE-15265:
----------------------------------------
{code}
* Configure which provider gets used with the configuration setting
"hbase.wal.provider". Available
* implementations:
* <ul>
* <li><em>defaultProvider</em> : whatever provider is standard for the hbase
version. Currently
* "filesystem"</li>
* <li><em>filesystem</em> : a provider that will run on top of an
implementation of the Hadoop
* FileSystem interface, normally HDFS.</li>
* <li><em>multiwal</em> : a provider that will use multiple "filesystem" wal
instances per region
* server.</li>
* </ul>
{code}
Now asyncfs also coming in. So how to setup a WAL system with new way of async
and also have N wals per RS?
