Hive Context and Mapr
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.
