#!/bin/bash
rm ~/log.log
echo "Please Input JobID:"
read NAME
map_log="/home/grid/hadoop-1.2.1/logs/userlogs/${NAME}/attempt_${NAME#*job_}_m_000000_0/stdout"
red_log="/home/grid/hadoop-1.2.1/logs/userlogs/${NAME}/attempt_${NAME#*job_}_r_000000_0/stdout"
echo "=========================================START=====================================" >> log.log
echo "Map:" >> log.log
cat $map_log >> log.log
echo "Reduce:" >> log.log
cat $red_log >> log.log
echo "==========================================END======================================" >> log.log
cat log.log
使用说明：
1.需要输入JobID，如：job_201407121609_0029
2.需要修改map_log和red_log这两个变量的值，以便适用于本机
3.注意：在JOB所在的机器运行，否则会报找不到目录
