Sqoop 的语法从数据库中存在的 100 个表中导入 5 个 - 不要使用 exclude 关键字？

Question

我在数据库中有 100 个表。我只想导入 5 个表。我不能t/don不能使用“--exclude”命令

Answer 1

This can be done by shell script.

1)Prepare a input file which has list of 5 DBNAME.TABLENAME 
2)The shell script will have this file as input, iterate line by line and execute sqoop statement for each line.
while read line;
do

    DBNAME=`echo $line | cut -d'.' -f1` 
    tableName=`echo $line | cut -d'.' -f2`


    sqoop import -Dmapreduce.job.queuename=$RM_QUEUE_NAME --connect '$JDBC_URL;databaseName=$DBNAME;username=$USERNAME;password=$PASSWORD' --table $tableName  --target-dir $DATA_COLLECTOR/$tableName  --fields-terminated-by '[=10=]1'  -m 1
