不同hadoop集羣之間遷移hive數據

#!/bin/bash
#set -x

DB=$1
#獲取hive表定義
ret=$(hive -e 'use ${DB};show tables;'|grep -v _es|grep -v _hb|grep -v importinfo)

for tem in $ret;
do
    hive -e "use ${DB};show create table $tem" >> /tmp/secha.sh
    echo -e ';\c' >> /tmp/secha.sh
done


#遷移hive的表數據
ret=$(hive -e 'use ${DB};show tables;'|grep -v _es|grep -v _hb|grep -v importinfo)

for tem in $ret;
do
    hadoop distcp hdfs://master:9000/user/hive/warehouse/${DB}.db/$tem hdfs://192.168.0.21:8020/user/hive/warehouse/${DB}.db/$tem
