I. Environment

1. Zk cluster

10.10.103.144:2181,10.10.103.246:2181,10.10.103.62:2181

2. Metastore database

10.10.103.246:3306

II. Installation

1. Install the configuration database

Yum-y install mysql55-server mysql55GRANT ALL PRIVILEGES ON metastore.* TO 'hive'@'localhost' IDENTIFIED BY' hive';GRANT ALL PRIVILEGES ON metastore.* TO 'hive'@'10.10.103.246' IDENTIFIED BY' hive';GRANT ALL PRIVILEGES ON metastore.* TO 'hive'@'127.0.0.1' IDENTIFIED BY' hive';CREATE DATABASE IF NOT EXISTS metastore;USE metastore;SOURCE / usr/lib/hive/scripts/metastore/upgrade/mysql/hive-schema-1.1.0.mysql.sql # execute this will report an error, and then execute the following sqlsource / usr/lib/hive/scripts/metastore/upgrade/mysql/hive-txn-schema-0.13.0.mysql.sql

2. Install hive

Yum-y install hive hive-jdbc hive-metastore hive-server2

3. Configuration

Vim / etc/hive/conf/hive-site.xml hive.execution.engine spark hive.enable.spark.execution.engine true spark.master yarn-client spark.enentLog.enabled true spark.enentLog.dir hdfs://mycluster:8020/spark-log spark.serializer org.apache.spark.serializer.KryoSerializer spark.executor.memeory 1g spark.driver.memeory 1g spark.executor.extraJavaOptions-XX:+PrintGCDetails-Dkey=value-Dnumbers= "one two three" hive.metastore.uris thrift://10.10.103.246:9083 Hive.metastore.local false javax.jdo.option.ConnectionURL jdbc:mysql://10.10.103.246/metastore javax.jdo.option.ConnectionDriverName com.mysql.jdbc.Driver javax.jdo.option.ConnectionUserName hive javax.jdo.option.ConnectionPassword hive datanucleus.autoCreateSchema false datanucleus.fixedDatastore true datanucleus.autoStartMechanism SchemaTable hive.support.concurrency true hive.zookeeper.quorum 10.10.103.144:2181,10.10.103.246:2181,10.10.103.62:2181 hive.aux.jars.path file:// / usr/lib/hive/lib/zookeeper.jar hive.metastore.schema.verificationfalse

4. Start the metastore service

/ etc/init.d/hive-metastore start

5. Verification
