hive元数据和hiveserver2启动脚本

鉴于在网上找了个现成的脚本hive元数据和hiveserver2的启动脚本bug不断，脚本不全，老是启动失败，所以不在偷懒重新整理如下，亲测可正常运行。

#!/bin/bash
HIVE_LOG_DIR=$HIVE_HOME/logs
if [ ! -d $HIVE_LOG_DIR ]
    then
        mkdir -p $HIVE_LOG_DIR
fi

if [ $# -lt 1 ]
then
    echo "Usage: $0{start|stop|status}"
    exit
fi

case $1 in
start){
    log_metastore="$HIVE_LOG_DIR/hivemetastore_$(date +%Y_%m_%d).log";
    log_hiveserver2="$HIVE_LOG_DIR/hiveserver2_$(date +%Y_%m_%d).log";
    echo "[info]------start metastore..."
    metastore_id=$(ps -ef | grep -i metastore | grep -v grep | awk {print $2})
    if [ $metastore_id ];then
        echo "[info]------metastore已经运行！"
    else
        nohup hive --service metastore -p 9083 >> $log_metastore 2>&1 &
        echo "[info]------metastore启动成功啦！"
    fi
    sleep 3
    echo "[info]------start hiveserver2..."
    hiveserver2_id=$(ps -ef | grep -i hiveserver2 | grep -v grep | awk {print $2})
    if [ $hiveserver2_id ];then
        echo "[info]------hiveserver2已经运行！"
    else
        nohup hiveserver2 >> $log_hiveserver2 2>&1 &
        echo "[info]------hiveserver2启动成功啦！"
    fi
};;
stop){
    echo "[info]------stop metastore"
    metastore_id=$(ps -ef | grep -i metastore | grep -v grep | awk {print $2})
    if [ $metastore_id ];then
        kill -9 $metastore_id
        k=$?
        if [ $k -eq 0 ]; then
            echo "[info]------metastore停止成功啦！"
        else
            echo "[info]------metastore停止失败啦！"
        fi
    else
        echo "[info]------metastore没有运行！"
    fi
    sleep 3
    echo "[info]------stop hiveserver2"
    hiveserver2_id=$(ps -ef | grep -i hiveserver2 | grep -v grep | awk {print $2})
    if [ $hiveserver2_id ];then
        kill -9 $hiveserver2_id
        k=$?
        if [ $k -eq 0 ];then
            echo "[info]------hiveserver2停止成功啦！"
        else
            echo "[info]------hiveserver2停止失败啦！"
        fi
    else
        echo "[info]------hiveserver2没有运行！"
    fi
};;
status){
    echo "[info]------check metastore status"
    metastore_id=$(ps -ef | grep -i metastore | grep -v grep | awk {print $2})
    if [ $metastore_id ];then
        echo "[info]------正在运行,进程号：$metastore_id"
    else
        echo "[info]------metastore没有运行！"
    fi
    echo "[info]------check hiveserver2 status"
    hiveserver2_id=$(ps -ef | grep -i hiveserver2 | grep -v grep | awk {print $2})
    if [ $hiveserver2_id ];then
        echo "[info]------正在运行,进程号：$hiveserver2_id"
    else
        echo "[info]------hiveserver2没有运行！"
    fi
};;
*)
    echo "Usage: $0{start|stop|status}"
    exit
;;
esac

运行结果如下：
