Subject [jira] [Commented] (HDFS-6065) HDFS zero-copy reads should return null on EOF when doing ZCR
Date Fri, 07 Mar 2014 01:04:46 GMT

Chris Nauroth commented on HDFS-6065:
-------------------------------------

The {{TestAclCLI}} failure is unrelated.  I've posted a patch on HDFS-6063 to fix that.

> It would be nice if the HDFS zero-copy reads mechanism returned an empty buffer on EOF.
 Currently, it throws UnsupportedOperationException on EOF when using zero-copy reads, which
seems confusing.
