Major Description
When I use rest call:
api/instance/triage/feed/A555dd292-5f43f281?start=abc&end=xyz&colo=*
Response is:
<?xml version="1.0" encoding="UTF-8"?><triage> <status>FAILED</status> <message>default/org.apache.falcon.FalconWebException::java.lang.IllegalArgumentException: abc is not a valid UTC string </message> <requestId>default/1511872682@qtp-1083962448-880 - 2ee2726c-83d2-443c-ac37-b49f668e550c </requestId> </triage>
But if I fire
api/instance/triage/feed/A555dd292-fb41610e?stort=abc&colo=*
the response has NPE without any hint as to what went wrong
<?xml version="1.0" encoding="UTF-8"?><triage> <status>FAILED</status> <message>default/org.apache.falcon.FalconWebException::java.lang.NullPointerException </message> <requestId>default/882508806@qtp-1083962448-906 - 3e8f0264-4ef8-4ccf-b526-3256745e1a52 </requestId> </triage>
