For {{TestRetryCacheWithHA.testUpdatePipeline}}, reopened HDFS-7524
For {{TestReencryptionWithKMS}}, some other test is failing in local run. In jenkins build,
{{TestReencryptionWithKMS#testReencryptNestedZones}} failed and in local run, {{TestReencryption#testReencryptionKMSDown}}
failed. 
Also on re-running, all tests passes.

Seems like some flaky tests in {{TestReencryptionWithKMS}}.
[~xiaochen]: do you mind giving final pass.
Changed the tests according to your suggestions from last comment.

> If I want to write to /.reserved/raw/<dir> and if that directory happens to be
