SparkStreaming任务保持运行，定时任务监控进程，保证不挂掉

cron任务：每隔1分钟启动脚本，检查进程是否运行。crontab -e

*/1 * * * * bash /data/spark/test.sh

检查进程，如果进程挂掉，重新启动Spark任务：给sh脚本添加权限，chmod 777 xx.sh

#!/bin/sh
is_Engine_exist=$(ps aux | grep LbsStreamingEngineTJ | grep -v grep | wc -l)

if [ $is_Engine_exist -eq 0 ];then

        echo 'Process Engine is down'

        echo 'Bring Engine up'

        strDate=`date +%Y%m%d%H%M%S`

        strStart="start Engine ${strDate}"

        echo "${strStart}" >> /data1/log.txt
