Subject [jira] [Created] (HDFS-6856) Send an OOB ack asynchronously
Date Fri, 15 Aug 2014 23:42:18 GMT
Brandon Li created HDFS-6856:

             Summary: Send an OOB ack asynchronously
                 Key: HDFS-6856
                 URL: https://issues.apache.org/jira/browse/HDFS-6856
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
            Reporter: Brandon Li
            Assignee: Brandon Li

As [~kihwal] pointed out in HDFS-6569,:
"One bad client may block this and prevent the message from being sent to the rest of "good"
clients. Unless a new thread is created (during shutdown!) to send an OOB ack asynchronously,
the blocking ack.readFields() call needs to be changed in order to delegate the message transmission
to the responder thread. "

This JIRA is to track the effort of sending OOB ack asynchronously.
