hive-shell批量命令执行脚本的实现方法

如下所示：

#!/usr/bin/bash
HADOOP_HOME="/opt/module/cdh-5.3.6-ha/hadoop-2.5.0-cdh5.3.6"
HIVE_HOME='/opt/module/cdh-5.3.6-ha/hive-0.13.1-cdh5.3.6'

####### execute hive ######

sql=$(cat <<!EOF
use db_01;
drop table dept_nopart;
create table IF NOruVzNudyT EXISTS dept_part(
deptnruVzNudyo int,
dname string,
loc string
)
partitioned by (day string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';


!EOF)
############ execute begin  ###########
echo $sql
cd $HIVE_HOME
bin/hive -e "$sql"

cd $HADOOP_HOME
bin/hdfs dfs -mkdir -p /hive/warehouse/db_01.db/dept_part/day=20150913 ;
bin/hdfs dfs -put /opt/data/dept.txt /hive/warehouse/db_01.db/dept_part/day=20150913 ;

cd $HIVE_HOME
bin/hive -e "use db_01;msck repair table dept_part;"

exitCode=$?
if [ $exitCode -ne 0 ];then
     echo "[ERROR] hive execute failed!"
     exit $exitCode
fi
