Subject [jira] [Commented] (ACCUMULO-2866) Default WAL size should be based on HDFS Block Size
Date Tue, 10 Jun 2014 14:30:02 GMT

Josh Elser commented on ACCUMULO-2866:
--------------------------------------

[~mdrob] do you still have issues here? Glancing at the LogSorter code, it appears that the
recovery files do already use the default HDFS block size.

> HBase automatically defaults their WAL size to 0.95 * HDFS block size. This makes a lot
of sense from a resource management perspective, and we should do the same.
