I'm attempting to run a pyspark script on BigInsights on Cloud 4.2 Enterprise that accesses a Hive table.
First I create the hive table:
[biadmin@bi4c-xxxxx-mastermanager ~]$ hive
hive> CREATE TABLE pokes (foo INT, bar STRING);
OK
Time taken: 2.147 seconds
hive> LOAD DATA LOCAL INPATH '/usr/iop/4.2.0.0/hive/doc/examples/files/kv1.txt' OVERWRITE INTO TABLE pokes;
Loading data to table default.pokes
Table default.pokes stats: [numFiles=1, numRows=0, totalSize=5812, rawDataSize=0]
OK
Time taken: 0.49 seconds
hive>
Then I create a simple pyspark script:
[biadmin@bi4c-xxxxxx-mastermanager ~]$ cat test_pokes.py
from pyspark import SparkContext
sc = SparkContext()
from pyspark.sql import HiveContext
hc = HiveContext(sc)
pokesRdd = hc.sql('select * from pokes')
print( pokesRdd.collect() )
I attempt to execute with:
[biadmin@bi4c-xxxxxx-mastermanager ~]$ spark-submit \
--master yarn-cluster \
--deploy-mode cluster \
--jars /usr/iop/4.2.0.0/hive/lib/datanucleus-api-jdo-3.2.6.jar, \
/usr/iop/4.2.0.0/hive/lib/datanucleus-core-3.2.10.jar, \
/usr/iop/4.2.0.0/hive/lib/datanucleus-rdbms-3.2.9.jar \
--files /usr/iop/4.2.0.0/hive/conf/hive-site.xml \
test_pokes.py
However, I encounter the error:
You must build Spark with Hive. Export 'SPARK_HIVE=true' and run build/sbt assembly
Traceback (most recent call last):

The solution was to use hive-site.xml from the spark-client folder:
