Eli Collins created HDFS-4000:
---------------------------------
Summary: TestParallelLocalRead fails with "input ByteBuffers must
be direct buffers"
Key: HDFS-4000
URL: https://issues.apache.org/jira/browse/HDFS-4000
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.0.3-alpha
Reporter: Eli Collins
Assignee: Colin Patrick McCabe
I think this may be related to HDFS-3753, passes when I revert it. Here's
failure. Looks like it needs the same fix as TestShortCircuitLocalRead, not
sure why that didn't show up in the jenkins run.
