UENISHI Kota created HDDS-5393:
----------------------------------
Summary: 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
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.
