Dilli Arumugam created KNOX-163:
-----------------------------------
Summary: job submission through knox-webchat results in
NullPointerException
Key: KNOX-163
URL: https://issues.apache.org/jira/browse/KNOX-163
Project: Apache Knox
Issue Type: Bug
Reporter: Dilli Arumugam
Hitting a NullPointerException while trying to submit a job through knox ->
webhcat.
The same use case works when there is no knox in path.
Curl session:
curl -k -i -u guest:guest-password -X POST \
-d jar=/user/guest/tmp/test/lib/wordcount.jar -d class=WordCountTem\
-d arg=/user/guest/tmp/test/input -d arg=/user/guest/tmp/test/output \
https://localhost:8443/gateway/sandbox/templeton/v1/mapreduce/jar
Pasting what I think is relevant from the stack trace on shown on console:
<h3>Caused by:</h3><pre>java.lang.NullPointerException

It appears that query string happens to be null.
The query string is not expected to be null here.
Would try to debug tomorrow.
