Set Hive TBLPROPERTIES using (py)Spark
I need to set a custom property in one of my Hive tables using pySpark.
Normally, I would just run this command in any Hive interface to do it:
ALTER TABLE table_name SET TBLPROPERTIES ('key1'='value1');
But the question is, can I accomplish the same within a pySpark script?
Thanks!

Well, that was actually easy... it can be set using sqlContext in pySpark:
sqlContext.sql("ALTER TABLE table_name SET TBLPROPERTIES('key1' = 'value1')")
It will return an empty DataFrame: DataFrame
But the property is actually present on the target table. It can be similarly retrieved using:
sqlContext.sql("SHOW TBLPROPERTIES table_name('key1')").collect()[0].asDict()
'value': u'value1'
