Subject [jira] [Commented] (ACCUMULO-3722) DFSInputStream being closed multiple times
Date Mon, 13 Apr 2015 18:51:14 GMT

Josh Elser commented on ACCUMULO-3722:
--------------------------------------

I haven't a clue, tbh. The RFile/BCFile code is one area I have not delved into in great depth
yet. I can test this if you'd like. I have a setup already. Hadoop-2.7.0 is incoming too,
FTR.

> Running on top of Hadoop 2.7.0-SNAPSHOT (or a version with HDFS-7494 applied), will result
in lots of warnings from DFSInputStream in the TabletServer.

that.
