[jira] [Commented] (TEZ-884) Add parameter checking for context related user API's

    [ https://issues.apache.org/jira/browse/TEZ-884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918435#comment-13918435 ] 

Siddharth Seth commented on TEZ-884:
------------------------------------

Do we need to put in a maven dependency to pull in "@ Nullabe". I believe it works rightnow because it's pulled in explicitly by Hadoop.

> I'm taking TEZ-865, and struggling with NPE. It's very effective to avoid NPE by adding @Nullable annotation and assert arguments by Preconditions.checkNotNull at API level.
