Impala编译部署-5单机部署-1

1.1  文件拷贝

将编译生成并复制的可执行文件，一起拷贝到本机某目录下，比如/root/impala2

1.2  操作系统

1.2.1 安装JDK

安装JDK。方法同编译部分。

1.2.2 环境变量

~/.bashrc

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.65-3.b17.el7.x86_64

export PATH=$PATH:$JAVA_HOME/bin

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

 

 

~/.bash_profile

 

export IMPALA_HOME=/root/impala2

source /etc/default/impala

 

1.3  配置

1.3.1 Impala配置文件

将impala运行必须的配置放到文件/etc/default/impala中，大概内容如下

 

IMPALA_STATE_STORE_HOST=127.0.0.1

IMPALA_STATE_STORE_PORT=24000

IMPALA_BACKEND_PORT=22000

IMPALA_LOG_DIR=/var/log/impala

IMPALA_CATALOG_SERVICE_HOST=127.0.0.1

 

export IMPALA_STATE_STORE_ARGS=${IMPALA_STATE_STORE_ARGS:- 

-log_dir=${IMPALA_LOG_DIR} -state_store_port=${IMPALA_STATE_STORE_PORT}}

 

export IMPALA_SERVER_ARGS=" 

-log_dir=${IMPALA_LOG_DIR} 

-catalog_service_host=${IMPALA_CATALOG_SERVICE_HOST} 

-state_store_port=${IMPALA_STATE_STORE_PORT} 

-use_statestore 

-state_store_host=${IMPALA_STATE_STORE_HOST} 

-be_port=${IMPALA_BACKEND_PORT}"

 

export ENABLE_CORE_DUMPS=${ENABLE_COREDUMPS:-false}

 

export IMPALA_CATALOG_ARGS=" 

-catalog_service_host=${IMPALA_CATALOG_SERVICE_HOST} 

-catalog_service_port=26000"

 

export HADOOP_HOME="${IMPALA_HOME}/hadoop/"

export PATH=$PATH:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin

 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HADOOP_HOME/lib/native

export LD_LIBRARY_PATH=$IMPALA_HOME/lib64/:$LD_LIBRARY_PATH

 

for f in $IMPALA_HOME/dependency/*.jar; do

    export CLASSPATH=$CLASSPATH:$f

done

export CLASSPATH=$CLASSPATH:/etc/hadoop/

 

export CATALOGCMD="${IMPALA_HOME}/be/catalog/catalogd ${IMPALA_CATALOG_ARGS}"

export STATESTORECMD="${IMPALA_HOME}/be/statestore/statestored ${IMPALA_STATE_STORE_ARGS}"

export IMPALADCMD="${IMPALA_HOME}/be/service/impalad ${IMPALA_SERVER_ARGS}"

 

1.3.2 hadoop配置文件

mv ${IMPALA_HOME}/etc/hadoop   /etc
