[jira] [Created] (HDFS-16518) KeyProviderCache does not get closed in ShutdownHookManager

Lei Yang created HDFS-16518:
-------------------------------

             Summary: KeyProviderCache does not get closed in ShutdownHookManager
                 Key: HDFS-16518
                 URL: https://issues.apache.org/jira/browse/HDFS-16518
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 2.10.0
            Reporter: Lei Yang


The cache has ttl and can close KeyProvider when cache entry is expired.

In KeyProviderCache, we should add ShutdownHookManager to clean up all keyprovider instances in the cache when jvm shuts down.
