Date Fri, 11 Mar 2016 06:21:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15190510#comment-15190510
] 

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?
