Question

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：

Answer 1

--split-by Student.id应为--split-by id

sqoop自由格式查询导入到HBase不起作用
