I'm trying to use hive warehouse connector
and spark
on hdp 3.1
and getting exception even with simplest example (below).
The class causing problems: JaninoRuntimeException
- is in org.codehaus.janino:janino:jar:3.0.8
(dependency of spark_sql) and in com.hortonworks.hive:hive-warehouse-connector_2.11:jar
.
I've tried to exclude janino library from spark_sql, but this resulted in missing other classes from janino. And I need hwc to for the new functionality.
Anyone had same error? Any ideas how to deal with it?
I'm getting error:

def main(args: Array[String]): Unit = {
val ss = SparkSession.builder()
.config("spark.sql.hive.hiveserver2.jdbc.url", "nnn")
.master("local[*]").getOrCreate()
import ss.sqlContext.implicits._
val rdd = ss.sparkContext.makeRDD(Seq(1, 2, 3, 4, 5, 6, 7))
rdd.toDF("col1").show()
val hive = HiveWarehouseSession.session(ss).build()
}
}
After some investigation I've discovered that the presence of error depends on the order of libraries in classpath
.
For unknown reason when I was running this project in IntelliJ IDEA the classpath was always with random order and the app was failing and succeeding randomly.
In the end - HiveWarehouseConnector
jar in classpath
should be after Spark Sql
jar.
UPDATE
As suggested in this answer - the order inside IntelliJ IDEA can be changed in dependencies tab.
Otherwise - I was not able to solve this issue for IntelliJ - the order was always random, but when i executed program outside of IntelliJ - I set the order I needed.
