Hadoop分支
- Apache
- Cloudera
- Hortonworks
本文是采用Cloudera分支的hadoop。
下载cdh-5.3.6 版本
下载地址:http://archive.cloudera.com/cdh5/cdh/5/
各组件版本一定保持一致。
- cdh5.3.6-snappy-lib-natirve.tar.gz
- hadoop-2.5.0-cdh5.3.6.tar.gz
- hive-0.13.1-cdh5.3.6.tar.gz
- sqoop-1.4.5-cdh5.3.6.tar.gz
安装配置
- 配置好jdk
- 上传到ubuntu /opt/software/cdh。
- tar -zxvf hadoop-2.5.0-cdh5.3.6.tar.gz -C /opt/cdh-5.3.6
- tar -zxvf hive-0.13.1-cdh5.3.6.tar.gz -C /opt/cdh-5.3.6

格式化namenode
cd /opt/cdh-5.3.6/hadoop-2.5.0-cdh5.3.6
bin/hdfs namenode -format
启动
sbin/hadoop-daemon.sh start namenode
sbin/hadoop-daemon.sh start datanode
sbin/yarn-daemon.sh start resourcemanager
sbin/yarn-daemon.sh start nodemanager
sbin/mr-jobhistory-daemon.sh start historyserver
检查jps:
- 1905 NameNode
- 2354 NodeManager
- 2499 JobHistoryServer
- 2084 ResourceManager
- 1991 DataNode
- 2538 Jps
访问:http://hp-expert.tianpo.com:50070/ 如果打不开,检查是否有端口在监听:netstat –ant 50070
检查host配置:格式为(不能以用127.0.0.1):IP 域名
配置hive
配置hive-env.sh
# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/opt/cdh-5.3.6/hadoop-2.5.0-cdh5.3.6
# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/opt/cdh-5.3.6/hive-0.13.1-cdh5.3.6/conf
配置hive-log4j.properties
hive.log.threshold=ALL
hive.root.logger=WARN,DRFA
hive.log.dir=/opt/cdh-5.3.6/hive-0.13.1-cdh5.3.6/logs
hive.log.file=hive.log
配置hive.site.xml(touch hive.site.xml)
