Weiwei Yang created HDFS-11873:
----------------------------------
Summary: Ozone: Object store handler cannot serve requests from
same http client
Key: HDFS-11873
URL: https://issues.apache.org/jira/browse/HDFS-11873
Project: Hadoop HDFS
Issue Type: Sub-task
Components: HDFS-7240
Reporter: Weiwei Yang
Assignee: Weiwei Yang
Priority: Critical
This issue was found when I worked on HDFS-11846. Instead of creating a new
http client instance per request, I tried to reuse {{CloseableHttpClient}} in
{{OzoneClient}} class in a {{PoolingHttpClientConnectionManager}}. However,
every second request from the http client hangs, which could not get dispatched
to {{ObjectStoreJerseyContainer}}. There seems to be something wrong in the
netty pipeline, this jira aims to 1) fix the problem in the server side 2) use
the pool for client http clients to reduce the resource overhead.
