Weiwei Yang commented on HDFS-12488:
------------------------------------

Hi [~anu]/[~xyao]

Could you please take a look at this problem? I marked this as a task before merge. I did a quick look, I think the patch might end up with modifying more than 10 classes so I want to make sure the proposal looks good then start to work on a patch.

Thank you.

> 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.
