How to connect Spark SQL to remote Hive metastore (via thrift protocol) with no hive-site.xml?

Question

I\'m using HiveContext with SparkSQL and I\'m trying to connect to a remote Hive metastore, the only way to set the hive metastore is through including the hive-site.xml on

Answer 1

Below code worked for me. We can ignore the config of hive.metastore.uris for local metastore, spark will create hive objects in spare-warehouse directory locally.

import org.apache.spark.sql.SparkSession;

object spark_hive_support1 
{
  def main (args: Array[String]) 
   {
    val spark = SparkSession
      .builder()
      .master("yarn")
      .appName("Test Hive Support")
      //.config("hive.metastore.uris", "jdbc:mysql://localhost/metastore")
      .enableHiveSupport
      .getOrCreate();

    import spark.implicits._

    val testdf = Seq(("Word1", 1), ("Word4", 4), ("Word8", 8)).toDF;
    testdf.show;
    testdf.write.mode("overwrite").saveAsTable("WordCount");
  }
}
