Weiwei Yang updated HDFS-11846:
-------------------------------
Description:
There are several problems
# Http clients in {{OzoneVolume}}, {{OzoneBucket}} and {{OzoneClient}} are
created per request, per [Reuse of HttpClient
instance|http://hc.apache.org/httpclient-3.x/performance.html#Reuse_of_HttpClient_instance]
doc, proposed to reuse the http client instance to reduce the over head.
# Some resources in these classes were not properly cleaned up. E.g the http
connection, HttpGet/HttpPost requests.
This jira's purpose is to fix these issues and investigate how we can improve
the client.
was:There are some http clients in {{OzoneVolume}}, {{OzoneBucket}} and
{{OzoneClient}} are not properly closed which would leak resource leaks. This
jira's purpose is to fix these issues and investigate if we can reuse some of
http connections for better performance.
