[jira] [Commented] (YARN-5271) ATS client doesn't work with Jersey 2 on the classpath

["Li Lu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-5271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15850784#comment-15850784 ] 

Li Lu commented on YARN-5271:
-----------------------------

Quick note: are we catching an error here and disables timeline service based on this? Catching errors seems to be inadequate as per Java API doc:
bq. An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. 
(https://docs.oracle.com/javase/7/docs/api/java/lang/Error.html)

Reopen this JIRA for more investigation.

> see SPARK-15343 : once Jersey 2 is on the CP, you can't instantiate a timeline client, *even if the server is an ATS1.5 server and publishing is via the FS*
