sqoop自由格式查询导入到HBase不起作用

标签: hbase sqoop

我已将sqoop表导入到HBase,如下所示:

sqoop import --connect jdbc:mysql://${mysql-server-address}/test -username root -password admin --table Student --hbase-create-table --hbase-table student --column-family i

下一步,我也试图让自由格式查询工作,但是,我尝试的sqoop命令无法按预期工作,没有任何内容从源表导入到目标HBase表。

sqoop import --connect jdbc:mysql://${mysql-server-address}/test -username root -password admin --query 'SELECT id, name from Student where $CONDITIONS' --split-by Student.id --hbase-create-table --hbase-table student --column-family i

第二个sqoop命令中是否有任何遗漏?该文件在HBase导入方面非常有限。

如果有帮助,这里是来自命令2的日志:
