IP | 主機名 | 部署 |
192.168.2.10 | bi10 | hadoop-2.6.2,hive-1.2.1,hive metastore |
192.168.2.12 | bi12 | hadoop-2.6.2,hive-1.2.1,hive metastore |
192.168.2.13 | bi13 | hadoop-2.6.2,hive-1.2.1 |
新建用戶hive,密碼hive,然后授權。數(shù)據(jù)庫IP:192.168.2.11 端口:3306
CREATE USER 'hive'@'%' IDENTIFIED BY 'hive'; GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION; FLUSH PRIVILEGES; CREATE DATABASE hive; alter database hive character set latin1;
解壓hive-1.2.1到/home/hadoop/work/hive-1.2.1目錄下,然后修改配置文件
修改hive-site.xml,進入hive的conf目錄下
[hadoop@bi13 conf]$ mv hive-env.sh.template hive-site.xml [hadoop@bi13 conf]$ vim hive-site.xml
hive-site.xml,參數(shù)說明:
hive.metastore.warehouse.dir | hive數(shù)據(jù)倉庫在hdfs中的位置,由于hadoop集群采用了ha的方式,所以在這里使用hdfs://masters/user/hive/warehouse,而沒有具體的namenode主機+端口 |
hive.metastore.uris | 這個使用hive使用metastore server的端口配置,我們使用默認的9083端口 |
hive.exec.scratchdir | 同樣,由于ha的配置,我們使用hdfs://masters/user/hive/tmp |
javax.jdo.option.ConnectionPassword | mysql數(shù)據(jù)庫密碼 |
javax.jdo.option.ConnectionDriverName | mysql數(shù)據(jù)庫驅動 |
javax.jdo.option.ConnectionURL | mysql數(shù)據(jù)庫URL |
javax.jdo.option.ConnectionUserName | mysql數(shù)據(jù)庫用戶名 |
hive.querylog.location hive.server2.logging.operation.log.location hive.exec.local.scratchdir hive.downloaded.resources.dir | 這些配置項的value值必須寫成具體的路徑,否在會出現(xiàn)問題 |
<property> <name>hive.metastore.warehouse.dir</name> <value>hdfs://masters/user/hive/warehouse</value> <description>location of default database for the warehouse</description> </property> <property> <name>hive.metastore.uris</name> <value>thrift://bi10:9083,thrift://bi12:9083</value> <description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description> </property> <property> <name>hive.exec.scratchdir</name> <value>hdfs://masters/user/hive/tmp</value> <description>HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/<username> is created, with ${hive.scratch.dir.permission}.</description> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>hive</value> <description>password to use against metastore database</description> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> <description>Driver class name for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://192.168.2.11:3306/hive?createDatabaseIfNotExist=true</value> <description>JDBC connect string for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hive</value> <description>Username to use against metastore database</description> </property> <property> <name>hive.querylog.location</name> <value>/home/hadoop/work/hive-1.2.1/tmp/iotmp</value> <description>Location of Hive run time structured log file</description> </property> <property> <name>hive.server2.logging.operation.log.location</name> <value>/home/hadoop/work/hive-1.2.1/tmp/operation_logs</value> <description>Top level directory where operation logs are stored if logging functionality is enabled</description> </property> <property> <name>hive.exec.local.scratchdir</name> <value>/home/hadoop/work/hive-1.2.1/tmp/${system:user.name}</value> <description>Local scratch space for Hive jobs</description> </property> <property> <name>hive.downloaded.resources.dir</name> <value>/home/hadoop/work/hive-1.2.1/tmp/${hive.session.id}_resources</value> <description>Temporary local directory for added resources in the remote file system.</description> </property>
使用hive下面的jline-2.12.jar替代hadoop下面的jline-0.9.94.jar
mv hive-1.2.1/lib/jline-2.12.jar hadoop-2.6.2/share/hadoop/yarn/lib/ mv hadoop-2.6.2/share/hadoop/yarn/lib/jline-0.9.94.jar hadoop-2.6.2/share/hadoop/yarn/lib/jline-0.9.94.jar.bak
把以上操作復制到所有部署hive的機器上
分別在bi10和bi12下面啟動metastore service
nohup hive --service metastore > null 2>&1 &
進入hive,看是否有問題。如果存在問題是用hive --hiveconf hive.root.logger=DEBUG,console啟動,可以看到具體的日志。
