Description

When after evalute policy and then process the auditlog，need to obtain AuditHandler Object and AuthzAuditEvent object
(1) AuditHandler object obtained when init plugin according to the value of xasecure.audit.destination.db/solr/hdfs/...
(2) So, obtaining AuthzAuditEvent should also according to the value of xasecure.audit.destination.db/solr/hdfs/...,or when AuditHandler is null or dummyHandler, constructing AuthzAuditEvent object is useless which is very frequently called and thus result in the performance decline of service(hdfs namenode, kakfa broker,hiveserver2...)
