Configure the storage policy for WALs using the Command Line

You can configure the preferred HDFS storage policy for HBase's write-ahead log (WAL) replicas using the command line.

  • Paste the following XML into hbase-site.xml. Uncomment the <value> line that corresponds to your desired storage policy. 
    <property>
  <name>hbase.wal.storage.policy</name>
  <value>NONE</value>
  <!--<value>ONE_SSD</value>-->
  <!--<value>ALL_SSD</value>-->
</property>
  • Restart HBase. Changes will take effect for a given region during its next major compaction.
