Datanodes need to catch SocketTimeoutException and UnregisteredDatanodeException
--------------------------------------------------------------------------------
Key: HADOOP-289
URL: http://issues.apache.org/jira/browse/HADOOP-289
Project: Hadoop
Type: Bug
Components: dfs
Versions: 0.3.1
Reporter: Konstantin Shvachko
Assigned to: Konstantin Shvachko
Fix For: 0.3.2
- Datanode needs to catch SocketTimeoutException when registering otherwise it
goes down
the same way as when the namenode is not available (HADOOP-282).
- UnregisteredDatanodeException need to be caught for all non-registering
requests. The data
node should be shutdown in this case. Otherwise it will loop infinitely and
consume namenode resources.
