------------------------------------
Moved to MAPREDUCE, was in HDFS accidentally. Unsure yet if this is a problem
today, will check later.

> Key: MAPREDUCE-3442
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3442
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Devaraj Das
> Priority: Minor
>
> The Progress-report IPC clients don't wait for an invoked IPC to complete
> before sending another progress report. Since in the IPC server, handlers
> execute as threads, an old progress report might overwrite the status sent by
> a newer progress report. Making the progress report IPC methods return a
> boolean or something, and having the clients wait for the response to a
> progress report before sending the next one, should handle the issue.
