Description

Findbugs reports a false-positive issue.

new org.apache.hadoop.hbase.rest.client.Client(Cluster, String, Optional, Optional) may fail to clean up java.io.InputStream

Try-with-resource block is used so the resource is cleaned up but findbugs thinks it otherwise. I tried to reproduce the problem locally and using the same docker container nightly test is using but findbugs did not report the problem for me.

Since branch-2.2 will be EOL soon I'd like to just add SuppressWarning to ignore the false-positive findbugs warning.
