Subject [jira] [Commented] (HDFS-8183) Erasure Coding: Improve DFSStripedOutputStream closing of datastreamer threads

Zhe Zhang commented on HDFS-8183:
---------------------------------

Thanks for working on this Rakesh. The patch LGTM. Only suggestion is to update the error
message _"Failed to shutdown streamer"_ to indicate which streams fail to close. 

Please see if you want to add a test here. Otherwise we can take the next chance to test this
change.

> The idea of this task is to improve closing of all the streamers. Presently if any of
the streamer throws an exception, it will returning immediately. This leaves all the other
streamer threads running. Instead its good to handle the exceptions of each streamer independently.
