I am using CDH5.5
I have a table created in HIVE default database and able to query it from the HIVE command.
Output
hive> use default;
OK
Time taken: 0.582 seconds
hive> show tables;
OK
bank
Time taken: 0.341 seconds, Fetched: 1 row(s)
hive> select count(*) from bank;
OK
542
Time taken: 64.961 seconds, Fetched: 1 row(s)
However, I am unable to query the table from pyspark as it cannot recognize the table.
from pyspark.context import SparkContext
from pyspark.sql import HiveContext
sqlContext = HiveContext(sc)
sqlContext.sql("use default")
DataFrame[result: string]
sqlContext.sql("show tables").show()
+---------+-----------+
|tableName|isTemporary|

sqlContext.sql("FROM bank SELECT count(*)")
