*  create\_hbase\_table.sh

#!/bin/bash
    #1,判断执行脚本时，是否输入正确的参数
    [[ $# < 1 ]] && echo "请输入hbase表名!" &&  exit 1
    
    #2,定义hbase表
    #hbase_table="'test111'"
    hbase_table="'$1'"
    cf="'f'"
    echo "输入的hbase表 ==>  $hbase_table $cf"
    
    #3,判断表是否已存在
    #echo "exists   $hbase_table  "| hbase shell  |grep 'does exist'
    echo `hbase shell <<EOF
    exists $hbase_table
    EOF` |grep 'does exist' 
    
    status=$?
    echo "exists ? ==> status=$status"
    if [ $status -eq 0 ];then
            echo "table exists..."; exit 0
    fi
    
    #创建表
    echo "table not exists ! ===> start creating...."
    #echo " create  $hbase_table , $cf "  |hbase shell 
    hbase shell <<EOF
    create $hbase_table , $cf 
    EOF
    
    #获取结果
    status=$?
    if [ $status -eq 0  ];then 
       echo "create succeed ! "
    else
       echo "error,create not done !"
    fi
