Hi Sourav,
1.5.1 has been added recently to the list of supported versions.
Internally spark interpreter will check against a list of supported
versions, before running.
This list is here:
spark/src/main/java/org/apache/zeppelin/spark/SparkVersion.java
This commit introduced the new spark version support :

upgrade spark to 1.5.1
simple & self-explanatory
Author: tribbloid <pc...@uow.edu.au>
Closes #333 from tribbloid/spark-1.5.1 and squashes the following
commits:
10d9465 [tribbloid] add spark 1.5.1 into the version list
b042fc5 [tribbloid] upgrade spark to 1.5.1
You can build zeppelin from master, then it will work with spark 1.5.1
Best Regards
Yash

When the winds that blow are merely breeze
Learn from nature, from birds and bees
Live your life in love, and let joy not cease.
