> 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.
