[jira] [Created] (SPARK-10961) Specified metastore 0.12.0 but
spark-shell still using metastore classes for 0.13+
Curtis Wilde created SPARK-10961:
------------------------------------
Summary: Specified metastore 0.12.0 but spark-shell still using metastore classes for 0.13+
Key: SPARK-10961
URL: https://issues.apache.org/jira/browse/SPARK-10961
Project: Spark
Issue Type: Bug
Components: Spark Shell, SQL
Affects Versions: 1.5.1
Reporter: Curtis Wilde
After setting metastore to 0.12.0 in {{spark-defaults.conf}}, spark-shell still uses some classes from 0.13 or above. The method {{get_functions}} is not found in {{org.apache.hadoop.hive.metastore.HiveMetaStore.java}} until 0.13.x.
>From {{spark-defaults.conf}}
{{spark.sql.hive.metastore.jars /usr/lib/spark/lib/commons-logging-1.1.1.jar:/usr/lib/spark/lib/hadoop-client-2.2.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hadoop-common-2.2.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-common-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-exec-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-metastore-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-serde-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/slf4j-api-1.7.5.jar:/usr/lib/spark/lib/slf4j-log4j12-1.7.5.jar:/usr/lib/spark/lib/hadoop-mapreduce-client-core-2.2.0.2.0.10.0-1.jar:/usr/lib/spark/lib/commons-configuration-1.6.jar:/usr/lib/spark/lib/commons-lang-2.6.jar:/usr/lib/spark/lib/hadoop-auth-2.2.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-jdbc-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-contrib-0.12.0.2.0.10.0-1.jar:/usr/lib/spark/lib/hive-cli-0.12.0.2.0.10.0-1.jar}}

Output from spark-shell:
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/lib/spark-1.5.1-bin-hadoop2.3/lib/spark-assembly-1.5.1-hadoop2.3.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
