<title>Distributed Log Splitting is on by default </title>
<para>Previous, WAL logs on crash were split by the Master alone. In 0.92.0, log
splitting is done by the cluster (See See “HBASE-1364 [performance] Distributed
splitting of regionserver commit logs”). This should cut down significantly on the
splitting of regionserver commit logs” or see the blog post
<link xlink:href="http://blog.cloudera.com/blog/2012/07/hbase-log-splitting/">Apache HBase Log Splitting</link>).
This should cut down significantly on the
amount of time it takes splitting logs and getting regions back online again.
