Hi,
I'm trying to run SQL query on Hive table which is stored on HBase.
I'm using:
- Spark 1.6.0
- HDP 2.2
- Hive 0.14.0
- HBase 0.98.4
I managed to configure working classpath, but I have following problems:
1) I have UDF defined in Hive Metastore (FUNCS table).
Spark cannot use it..
File "/opt/spark/python/lib/py4j-0.9-src.zip/py4j/protocol.py", line 308,
in get_return_value
py4j.protocol.Py4JJavaError: An error occurred while calling o51.sql.

2) When I'm using SQL without this function Spark tries to connect to
Zookeeper on localhost.
I make a tunnel from localhost to one of the zookeeper servers but it's not
a solution.

3) After making tunel I'm getting NPE.

Do you have any ideas how to resolve those problems ?
