Hive Context and Mapr

[Addanki, Santosh Kumar]

Hi

We are currently using Mapr Distribution.

To read the files  from the file system we specify as follows  :

test = sc.textFile("mapr/mycluster/user/mapr/test.csv")

This works fine from Spark Context.

But ...

Currently we are trying to create a table in hive using the hiveContext from 
Spark.

So when I specify something like

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

hc.sql("Create table deleteme_1 " + createString )

hc.sql("LOAD DATA LOCAL INPATH ' mapr/BI2-104/user/mapr/test.csv' INTO TABLE 
deleteme_1")

We  get the following  error

FAILED: RuntimeException java.io.IOException: No FileSystem for scheme: maprfs


An error occurred while calling o79.sql.
