Raghu Angadi commented on HADOOP-2974:
--------------------------------------
given this jira and HADOOP-2971 , it might be better to revert HADOOP-2346 for
now. Some of these might not be in our hands to fix. HADOOP-2346 is implemented
based on JavaDoc for SelectableChannels stuff. I will see.

> Key: HADOOP-2974
> URL: https://issues.apache.org/jira/browse/HADOOP-2974
> Project: Hadoop Core
> Issue Type: Bug
> Components: ipc
> Affects Versions: 0.17.0
> Environment: windows
> Reporter: Mukund Madhugiri
> Assignee: Raghu Angadi
> Priority: Blocker
> Fix For: 0.17.0

>
> ipc unit tests fail due to connection errors:
> Failing tests:
> org.apache.hadoop.ipc.TestIPC.unknown
> org.apache.hadoop.ipc.TestIPCServerResponder.unknown
> org.apache.hadoop.ipc.TestRPC.testSlowRpc
> org.apache.hadoop.ipc.TestRPC.testCalls
> Changes:
> # HADOOP-2346. Utilities to support timeout while writing to sockets.
> DFSClient and DataNode sockets have 10min write timeout.
> # HADOOP-2906. Add an OutputFormat capable of using keys, values, and config
> params to map records to different output files.
> # HADOOP-2756. NPE in DFSClient while closing DFSOutputStreams under load.
> # HADOOP-2934. The namenode was encountreing a NPE while loading leases from
> the fsimage. Fixed.
> # HADOOP-2925. Fix HOD to create mapred system directory using a naming
> convention that will avoid clashes in multi-user shared cluster scenario.
> # HADOOP-2911. Make the information printed by the HOD allocate and info
> commands less verbose and clearer.
> # HADOOP-2883. Write failures and data corruptions on HDFS files. The write
> timeout is back to what it was on 0.15 release. Also, the datnodes flushes
> the block file buffered output stream before sending a positive ack for the
> packet back to the client.
> # HADOOP-2861. INCOMPATIBLE CHANGE. Improve the user interface for the HOD
> commands. Command line structure has changed.
