DFSOutputStream socket leak when cannot connect to DataNode
-----------------------------------------------------------
Key: HDFS-1118
URL: https://issues.apache.org/jira/browse/HDFS-1118
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.2, 0.20.1
Reporter: Zheng Shao
Assignee: Zheng Shao
The offending code is in {{DFSOutputStream.nextBlockOutputStream}}
This function retries several times to call {{createBlockOutputStream}}. Each
time when it fails, it leaves a {{Socket}} object in {{DFSOutputStream.s}}.
That object is never closed, but overwritten the next time
{{createBlockOutputStream}} is called.
