how to access SAP VORA tables in SparkR

[#1]

In the case of

Hi,

I want to access SAP HANA VORA tables in a sparkR and create models on VORA tables.

I am able to find code for hive table(HiveContext <- sparkRHive.init (sc)). Can somebody help me to understand how to create a VORA context.

Thank you for looking into my problem.

Vishal, you should be able to access VORA's with HANA's JDBC driver. You just need to then map it to a PySpark or SParkR context. Look it up, it's easy to find online... or let me know if you're stuck.

Thank you for the reply.

I ran the below function but the function is only available from 2.0

data <- read.jdbc(jdbcurl,"tablename", user ="user", password ="password")

I am currently using spark1.6.1 and can not upgrade.

Do you know any other alternative solution.

Hi, @vishal kuchhal

If you can connect via 2.0, it seems that you can do 1.6.1, too.

The following is supported Apache Spark 1.6.1.

R: http://spark.apache.org/docs/1.6.1/sql-programming-guide.html#tab_r_15

Scala: http://spark.apache.org/docs/1.6.1/sql-programming-guide.html#tab_scala_15

SQL: http://spark.apache.org/docs/1.6.1/sql-programming-guide.html#tab_sql_15

df <- loadDF(sqlContext, source="jdbc", url="jdbc:postgresql:dbserver", dbtable="schema.tablename")

val jdbcDF = sqlContext.read.format("jdbc").options(
  Map("url" -> "jdbc:postgresql:dbserver",
  "dbtable" -> "schema.tablename")).load()

CREATE TEMPORARY TABLE jdbcTable
USING org.apache.spark.sql.jdbc
OPTIONS (
  url "jdbc:postgresql:dbserver",
  dbtable "schema.tablename"
)
