[GitHub] [hadoop] omalley commented on pull request #4100: HDFS-16518: Close cached KeyProvider when DFSClient is closed

URL: https://github.com/apache/hadoop/pull/4100#issuecomment-1078244353


   I commented on the jira, but:
   
   I don't understand why this is required. Obviously at jvm shutdown the cache will be discarded. The order of shutdown hooks isn't deterministic, so using this isn't a fix against other shutdown hooks using the cache.
   
   Is there some other call to KeyProvider.close() that this should replace?
