Peter Bykov updated SPARK-21063:
Description:
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:1/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.
