我收到以下错误，请您为此提供解决方案

13/12/05 17:40:47 INFO manager.MySQLManager: Setting zero DATETIME behavior to convertToNull (mysql)
13/12/05 17:40:47 ERROR tool.ImportTool: Error during import: HBase jars are not present in classpath, cannot import to HBase!

Answer 1

Sqoop不附带HBase，因此您需要定义指向安装HBase的变量$ HBASE_HOME，例如：

export HBASE_HOME=/usr/lib/hbase
sqoop import ...

我如何将表从mysql导入到hbase？
