i am working with spark 1.3.0 (at python)

i have DF :

DF.show(3)

ID             Date       Hour     TimeInCluster Cluster Xcluster Ycluster

25342438156 2012-11-30 15:00:00 26            T       130270   165620

25342438156 2012-11-30 16:00:00 86            D       136850   177070

25342438156 2012-11-30 17:00:00 35            D       136850   177070

i am tring to save that DF into not exist hive table

how can i do that?

thank you

i change my code to :

sqlContext = HiveContext(sc)

FinalDf.write().mode(SaveMode.Overwrite).saveAsTable("myDB.sixuserstablediary")

but i got that error

py4j.protocol.Py4JJavaError: An error occurred while calling o280.apply.

You need to use Spark HiveContext

Import Spark HiveContex

from pyspark.sql import HiveContext
sqlContext = HiveContext(sc)

Create a temporary Table from the dataframe then insert into hive table by selecting data from temporary table.

// Register the dataframe
   df.registerTempTable("tbl_tmp")

   sqlContext.sql("create table default.tbl_hive_data as select * from tbl_tmp")
