sqoop |运行 sqoop 导入工具时出现空指针异常

Question

我正在尝试使用 sqoop 1.4.7 将 mysql 表导入配置单元。我已执行的命令

sqoop import --connect jdbc:mysql://localhost:3306/sb --username root --password xxxx --table sb_user --hive-import --create-hive-table --hive-table sqoop_import.test_from_sqoop --fields-terminated-by "," --bindir ./

但得到以下异常

Warning: /usr/local/sqoop/sqoop-1.4.7.bin__hadoop-2.6.0/../hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.

但是我可以成功执行下面的命令

sqoop list-tables --connect jdbc:mysql://localhost:3306/information_schema --username root -password xxxx

请帮帮我。谢谢

问题出在--bindir ./ 选项中。 Sqoop 尝试递归地添加 ./ (https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/util/FileListing.java#L72) 中的所有内容。检查此目录或更改它。
