[jira] [Commented] (HIVE-7517) RecordIdentifier overrides equals() but not hashCode()

    [ https://issues.apache.org/jira/browse/HIVE-7517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15888880#comment-15888880 ] 

Wei Zheng commented on HIVE-7517:
---------------------------------

In RecordIdentifier, "import java.util.Objects;" is not needed. In equals(), I think "if (other == null)" is still needed to avoid NPE.
