------------------------------------

             Summary: Registered UDFs does not work on Spark jobs initiated from Zeppelin
                 Key: ZEPPELIN-150
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-150
             Project: Zeppelin
          Issue Type: Bug
          Components: Interpreters
    Affects Versions: 0.5.0
         Environment: - Zeppelin 0.5.0
- Spark 1.3.1 on top yarn cluster
- Hadoop 2.4
            Reporter: Ophir Cohen


When trying using UDF from Zeppelin we get _java.lang.ClassNotFoundException: org.apache.zeppelin.spark.ZeppelinContext_
(see below the full exception).

h5. Steps to reproduce:
1. Create and register the UDF:
{code}
def getNum(): Int = {
    100
}
hc.udf.register("getNum",getNum _)
{code}

2. Try on exists table:
{code}
%sql select getNum() from filteredNc limit 1
{code}
Failed.

3. Directly on HiveContext:
{code}
hc.sql("select getNum() from filteredNc limit 1").collect
{code}
Failed.

h5. few insights
1. On Spark shell it works as expected.
2. This bug happened only with RDDs/tables that originated from external source (Hive/S3 parquet files). Creating new DataFrame and register it works as expected.

The (almost) full exception:
