Anu Engineer commented on HDFS-12488:
-------------------------------------
[~msingh] I am not sure that works, the reason we do list to understand how
many entries there. You are asking that we know it a priori. Not sure if that
will work. Generally, the way we deal with this kind of an issue is by defining
the maximum number of entries returned by the server in a list call. Do you
think that would address the issue you are pointing out?
> Ozone: OzoneRestClient needs to be configuration awareness

> Key: HDFS-12488
> URL: https://issues.apache.org/jira/browse/HDFS-12488
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Affects Versions: HDFS-7240
> Reporter: Weiwei Yang
> Assignee: Weiwei Yang
> Labels: ozoneMerge
>
> When I test ozone on a 15 nodes cluster with millions of keys, responses of
> rest client becomes to be slower. Following call times out after default 5s,
> {code}
> bin/hdfs oz -listBucket http://15oz1.fyre.ibm.com:9864/vol-0-84022 -user wwei
> Command Failed : {"httpCode":0,"shortMessage":"Read timed
> out","resource":null,"message":"Read timed
> out","requestID":null,"hostName":null}
> {code}
> Then I increase the timeout by explicitly setting following property in
> {{ozone-site.xml}}
> {code}
> <property>
> <name>ozone.client.socket.timeout.ms</name>
> <value>10000</value>
> </property>
> {code}
> but this doesn't work and rest clients are still created with default *5s*
> timeout. This needs to be fixed. Just like {{DFSClient}}, we should make
> {{OzoneRestClient}} to be configuration awareness, so that clients can adjust
> client configuration on demand.
