----------------------------------------
Assignee: Bharat Viswanadham
> Return latest version of key location for client on createKey
> -------------------------------------------------------------
>
> Key: HDDS-5393
> URL: https://issues.apache.org/jira/browse/HDDS-5393
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Client
> Reporter: UENISHI Kota
> Assignee: Bharat Viswanadham
> Priority: Major
> Fix For: 1.2.0
>
>
> HDDS-5243 was a patch for omitting unnecessary key locations for clients on
> reading. But the same warning of large response size observed in our cluster
> for putting data. The patch can also be ported for putting data, as long as
> until object versioning is supported.
> My hypothesis is: The large message was originally, and possibly maybe due to
> this warning and sudden connection close from client side on reading large
> message in Hadoop IPC layer, from Ozone Manager - which causes hopeless 15
> retries from RetryInvocationHandler. The retries create another entry in
> OpenKeyTable but they never moved to KeyTable because the key never gets
> commited.
