             Summary: WASB should configure client side socket timeout in 
storage client blob request options
                 Key: HADOOP-11959
                 URL: https://issues.apache.org/jira/browse/HADOOP-11959
             Project: Hadoop Common
          Issue Type: Bug
          Components: tools
            Reporter: Ivan Mitic
            Assignee: Ivan Mitic


On clusters/jobs where {{mapred.task.timeout}} is set to a larger value, we 
noticed that tasks can sometimes get stuck on the below stack.

{code}

The issue is that the storage client is by default not setting the socket 
timeout on its HTTP connections causing that in some (rare) circumstances we 
encounter a deadlock (e.g. whether the server on the other side just dies 
unexpectedly).  

The fix is to configure the maximum operation time on the storage client 
request options.
