             Summary: Error in ElasticSearchAuditDestination shutting down 
RestHighLevelClient client
                 Key: RANGER-4943
                 URL: https://issues.apache.org/jira/browse/RANGER-4943
             Project: Ranger
          Issue Type: Bug
          Components: audit
    Affects Versions: 2.5.0
            Reporter: FerArribas
            Assignee: FerArribas
             Fix For: 3.0.0


*Error encountered* -> ElasticSearchAccessAuditsServiceTest -> ERROR 
org.apache.ranger.audit.provider.BaseAuditHandler – Error sending message to 
ElasticSearch java.lang.RuntimeException: Cannot execute request; I/O reactor 
status: STOPPED</resthighlevelclient>.

*Details:*

Error in using a try-with-resources block in ElasticSearchAuditDestination 
because it closes the ElasticSearch client prematurely. In a try-with-resources 
block, any resource that implements the AutoCloseable interface will 
automatically close at the end of the block, which may cause the ElasticSearch 
client to close before its use is complete.  To avoid this problem, we remove 
the try-with-resources usage for the ElasticSearch client because it already 
explicitly closes the client when it is no longer needed, specifically in 
RestHighLevelClient which implements Closeable's close method.
