--------------------------------
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.
