the py script :

#!/usr/bin/env python
#coding=utf-8
from os.path import expanduser, join, abspath
from pyspark.sql import SparkSession
from pyspark.sql import Row
from pyspark.conf import SparkConf
def squared(s):
return s * s
# warehouse_location points to the default location for managed databases and
tables
warehouse_location = abspath('/group/user/yangtt/meta/hive-temp-table')
spark = SparkSession \
.builder \
.appName("Python_Spark_SQL_Hive") \
.config("spark.sql.warehouse.dir", warehouse_location) \
.config(conf=SparkConf()) \
.enableHiveSupport() \
.getOrCreate()
spark.udf.register("squared",squared)
spark.sql("show databases").show()
Q:why the spark load the different hive metastore
the yarn always use the DERBY?
17/09/14 16:10:55 INFO MetaStoreDirectSql: Using direct SQL, underlying DB is
DERBY
my current metastore is in mysql.
any suggest will be helpful.
thanks.
