CDH环境下HBase和MapReduce的集成

1.配置环境变量（每台机器都要配置）

vim /etc/profile

2.加入：

export HBASE_HOME=/opt/cloudera/parcels/CDH-5.14.4-1.cdh5.14.4.p0.3/lib/hbase
export HADOOP_HOME=/opt/cloudera/parcels/CDH-5.14.4-1.cdh5.14.4.p0.3/lib/hadoop

source /etc/profile

vim /etc/hadoop/conf/hadoop-env.sh

（每台机器都要加入）：

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/opt/cloudera/parcels/CDH-5.14.4-1.cdh5.14.4.p0.3/lib/hbase/lib/*

source /etc/hadoop/conf/hadoop-env.sh

6.测试
先重启一下集群

cd /opt/cloudera/parcels/CDH-5.14.4-1.cdh5.14.4.p0.3

测试

bin/yarn jar ./lib/hbase/lib/hbase-server-1.2.0-cdh5.14.4.jar rowcounter 表名
