Aaron T. Myers commented on HDFS-4831:
--------------------------------------
Good find, and thanks a lot for testing out the fix, Lenni.
+1, the patch looks good to me. I don't think tests are necessary for this
change since the issue is so difficult to reproduce. I also tested this by
running the following, since I'm not sure if test-patch runs with native
support:
{noformat}
$ mvn -Pnative clean test
-Dtest=TestParallelShortCircuitReadUnCached,TestParallelShortCircuitLegacyRead,TestParallelShortCircuitReadNoChecksum,TestShortCircuitLocalRead,TestParallelShortCircuitRead
{noformat}
All the tests passed as expected.
I'm going to commit this momentarily.
