start.sh 开始 copy_file.sh 并向其传递2个参数

yeasterday_with_dash=2017-01-31
today_without_dash=20170201

echo "-----------RUN copy mta-------------"
bash copy_file.sh mta $today_without_dash
echo "-----------RUN copy rcr-------------"
bash copy_file.sh rcr $today_without_dash
echo "-----------RUN copy sub-------------"
bash copy_file.sh sub $today_without_dash
``` `copy_file.sh` 用于检查目录是否存在，如果不存在，则创建它。

hdfs_dir=/apps/hive/warehouse/mydb.db/fct_evkuzmin/${2}/file_${1}

if hadoop fs -test -d $hdfs_dir ; then
echo "Directory "$hdfs_dir" exists"
else
hadoop fs -mkdir $hdfs_dir
echo "Creating "$hdfs_dir
fi

脚本似乎运行得很成功。
日志。

today_without_dash=20170201
-----------RUN copy mta-------------

但是没有创建实际的目录。有什么问题吗？
