Thanks for the nice feature. Could you rebase and trigger CI?

[echarles]

From https://s3.amazonaws.com/archive.travis-ci.org/jobs/88620950/log.txt, the build is success

[INFO] Zeppelin: Packaging distribution ................... SUCCESS [ 35.204 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 02:26 min

Any reason for the red flag on github?

Should I rebase and push again, or close/reopen to trigger the CI?

[Leemoonsoo]

it's because of

�[0K$ ./testing/startSparkCluster.sh 1.4.0 2.3
SPARK_HOME is /home/travis/build/apache/incubator-zeppelin/spark-1.4.0-bin-hadoop2.3 


No output has been received in the last 10 minutes, this potentially indicates a stalled build or something wrong with the build itself.

issue resolved by #380. This time, you'll need rebase and push to apply #380.

could this be ZEPPELIN_SERVER_CONTEXT_PATH?
there is a object called ZeppelinContext in the Spark interpreter group and this name might be confusing

[echarles]

Any more feedback on this?

[Leemoonsoo]

I'm not sure why CI is failing. You can trigger CI again.
And the branch seems removed, can not try anymore.

Please use #429 to track this.
