Problem

I have a problem to use hiveContext with zeppelin. For example this code does not works:

%pyspark
from pyspark.sql import HiveContext 
sqlContext = HiveContext(sc)
sample07 = sqlContext.table("default.sample_07")
sample07.show()
Here is the error displayed:
You must build Spark with Hive. Export 'SPARK_HIVE=true' and run build/sbt assembly

Solution

Even though you are logged in to Zeppelin UI as a user from AD/LDAP/local, the query gets executed as zeppelin user. Hence, zeppelin user needs to have a written permission to where hive.exec.local.scratchdir parameter indicates. As default, it is set to /tmp/<userName>. So, the following needs to exist in zeppelin node:

[root@dan2 ~]# ls -lrt /tmp
drwxr-xr-x. 20 zeppelin  zeppelin   4096 Mar 10 16:46 zeppelin
