Subject [jira] [Created] (HDFS-5172) Handle race condition for writes
Date Mon, 09 Sep 2013 04:43:52 GMT
Brandon Li created HDFS-5172:
--------------------------------

             Summary: Handle race condition for writes
                 Key: HDFS-5172
                 URL: https://issues.apache.org/jira/browse/HDFS-5172
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Brandon Li
            Assignee: Brandon Li


When an unstable write arrives, the following happens: 
1. retrieves the OpenFileCtx
2. create asyn task to write it to hdfs

The race is that, the OpenFileCtx could be closed by the StreamMonitor. Then step 2 will simply
return an error to the client.

This is OK before streaming is supported. To support data streaming, the file needs to be
reopened.
