Hudson commented on HDFS-4213: ------------------------------ Integrated in Hadoop-trunk-Commit #3078 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/3078/]) HDFS-4213. Add an API to hsync for updating the last block length at the namenode.

This jira implements this sync-with-updating-length by > 1) calling ClientProtocol#fsync(), and 2) adding a new field to > ClientProtocol#fsync() to indicate the length information. -- This message is automatically generated by JIRA.
