Yuming Wang commented on SPARK-21063:
-------------------------------------
[~pbykov], I just verified it. It can get the result without any specific
configuration if {{jdbc:hive2://remote.hive.local:10000/default}} is [Spark
hive-thriftserver|https://github.com/apache/spark/blob/master/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/HiveThriftServer2.scala].
But it will throw {{org.apache.thrift.TApplicationException}} if
{{jdbc:hive2://remote.hive.local:10000/default}} is
[hive-thriftserver|https://github.com/apache/hive/blob/master/service/src/java/org/apache/hive/service/server/HiveServer2.java],
So what is your {{jdbc:hive2://remote.hive.local:10000/default}}?

>
> Key: SPARK-21063
> URL: https://issues.apache.org/jira/browse/SPARK-21063
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, SQL
> Affects Versions: 2.1.0, 2.1.1
> Reporter: Peter Bykov
>
> Spark returning empty result from when querying remote hadoop cluster.
> All firewall settings removed.
> Querying using JDBC working properly using hive-jdbc driver from version 1.1.1
> Code snippet is:
> {code:java}
> val spark = SparkSession.builder
> .appName("RemoteSparkTest")
> .master("local")
> .getOrCreate()
> val df = spark.read
> .option("url", "jdbc:hive2://remote.hive.local:10000/default")
> .option("user", "user")
> .option("password", "pass")
> .option("dbtable", "test_table")
> .option("driver", "org.apache.hive.jdbc.HiveDriver")
> .format("jdbc")
> .load()
>
> df.show()
> {code}
> Result:
> {noformat}
> +-------------------+
> |test_table.test_col|
> +-------------------+
> +-------------------+
> {noformat}
> All manipulations like:
> {code:java}
> df.select(*).show()
> {code}
> returns empty result too.
