Description of PR

Depends on PR #6860

JIRA = HDFS-17540
The ekek cache warm up thread should not fail the whole warmup of other keys if an invalid key is encountered.
We have observed infinite retries to KMS if one of Encryption Key is not available.

Change it to

  • Continue to warmup other keys, throw IOException at last
  • Add a retry limit config

How was this patch tested?

Added unit test TestFSDirEncryptionZoneOp for retry behavior

I'm concerned will changing the contract of warmUpEncryptedKeys from

exception if any key isn't initialized

to

exception only if all keys can't be initialized

You can still like the number of retries, without changing the above.

Could you please to carve out the changes in hadoop-common into a separate PR. I'm suspecting this may be what is causing the CI tests to hang and fail.

Besides the CI tests, keeping the changes contained within a module is cleaner for maintainability and modularity.
