How to use Hive Metastore with MySQL (for Thrift Server or spark-shell)?

问题

I'm using Apache Spark 2.1.1 and I'd like to set it up with an external Hive metastore (for Spark Thrift Server specifically).

I have added hive-site.xml to $SPARK_HOME/conf folder that is as follows:

<?xml version="1.0"?>
<configuration>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://home.cu:3306/hive_metastore?createDatabaseIfNotExist=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=Europe/Berlin&amp;nullNamePatternMatchesAll=true </value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>

  <property>
    <name>javax.jdo.option.ConnectionDriverName</name>
    <value>com.mysql.jdbc.Driver</value>
    <description>Driver class name for a JDBC metastore</description>
  </property>

  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>hive</value>
    <description>username to use against metastore database</description>
  </property>

  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>hive</value>
    <description>password to use against metastore database</description>
  </property>
  <property>
    <name>hive.metastore.schema.verification</name>
    <value>false</value>
    <description>password to use against metastore database</description>
  </property>

  <property>
    <name>hive.metastore.warehouse.dir</name>
    <value>hdfs://spark-master.cu:9000/value_iq/hive_warehouse/</value>
    <description>Warehouse Location</description>
  </property>
</configuration>

Whenever I try to run spark-shell or Spark Thrift Server they attempt to create the Hive metastore on MySQL (as there is no metastore yet) and they fails with the following error:

17/07/13 19:57:55 ERROR Datastore: Error thrown executing ALTER TABLE `PARTITIONS` ADD COLUMN `TBL_ID` BIGINT NULL : Table 'hive_metastore.partitions' doesn't exist

I have found the problem, it was related with the MySQL driver, I was using mysql-connector-java-6.0.6-bin.jar and I have replaced it with and old one mysql-connector-java-5.1.23-bin.jar and now it works.

I don't think that your warehouse dir property is configured properly, it should be a path on HDFS

<configuration>
<property>
    <name>hive.metastore.uris</name>
    <value>thrift://maprdemo:9083</value>
</property>
<property>
    <name>hive.metastore.warehouse.dir</name>
    <value>/user/hive/warehouse</value>
</property>

I've tried with different versions of spark to migrate the metadata management from derby to mysql/postgres and I'm successful with spark-2.2.1 onwards. The before versions wouldn't let me migrate to other databases. It's purely version dependency that they have with the spark. My suggestion try upgrading the spark version to 2.2.1 and you should be good to go!!
