Subject [jira] Created: (HADOOP-2974) ipc unit tests fail due to connection errors
Date Fri, 07 Mar 2008 22:25:46 GMT
ipc unit tests fail due to connection errors
--------------------------------------------

                 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: Robert Chansler
            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.
