             Summary: Interrupt DataStreamer thread
                 Key: HDFS-15865
                 URL: https://issues.apache.org/jira/browse/HDFS-15865
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
            Reporter: Karthik Palanisamy


Have noticed HiveServer2 halts due to DataStreamer#waitForAckedSeqno. 

I think we have to interrupt DataStreamer if no packet ack(from datanodes). It 
likely happens with infra/network issue.
