Impala任务程序cancle

#!/usr/bin/python
# -*- coding:utf-8 -*-

'''
功能：
    1. 取消内存占用超过一定值 执行时间超过一定值 查杀某些用户的任务 排除某些查询ID
用例：
    #取消查询QUERY，用户是zhagnwei  超过时间：10s  内存超过1E7
    python cancle_impala_task.py  1E7 10000  "select" "zhangsan" ""
    
    #取消查询DDL，用户是zhagnwei  超过时间：10s
    python cancle_impala_task.py  ""  10000  "invalidat" "zhangsan" ""
    
    #取消查询DDL，用户是zhagnwei  超过时间：10s  排除查询ID
    python cancle_impala_task.py  ""  10000  "invalidat" "zhangsan" "000000000e000000:2000000000000000"
        
说明：
    1E8  = 100M
    1E9  = 1G
    1E10 = 10G
    1E11 = 100G
