Subject [jira] [Commented] (HDFS-12268) Ozone: Add metrics for pending storage container requests
Date Tue, 08 Aug 2017 23:52:00 GMT

Anu Engineer commented on HDFS-12268:
-------------------------------------

+1, on this change. Thanks for catching this issue. 

Do you think we can maintain average time per op. So we can print out the performance from
the client point of view?  There is also an added detail that from the ozone-client perspective
we create one XcieverClient per pipeline( a set of datanodes). So when we close the XcieverClient,
we should probably collect this info.

>  As storage container async interface has been supported after HDFS-11580, we need to
keep an eye on the queue depth of pending container requests. It can help us better found
if there are some performance problems.
