> 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.
