workflow调度使用sqoop组件，query中sql之间必须用tab键分割，workflow在解析配置文件时，无法识别空格，只能使用tab键， 否则会报错，例如 --query "SELECT DROP_PARTITION('table_name','${dt}')"
报错信息如下：
2562 [main] ERROR org.apache.sqoop.tool.BaseSqoopTool - Error parsing arguments for eval: 2016-10-11 16:27:21,730 ERROR [main] tool.BaseSqoopTool (BaseSqoopTool.java:hasUnrecognizedArgs(304)) - Error parsing arguments for eval: 2562 [main] ERROR org.apache.sqoop.tool.BaseSqoopTool - Unrecognized argument: DROP_PARTITION('table_name','20160930')" 2016-10-11 16:27:21,730 ERROR [main] tool.BaseSqoopTool (BaseSqoopTool.java:hasUnrecognizedArgs(307)) - Unrecognized argument: DROP_PARTITION('table_name','20160930')"
用tab替换sql中的空格，问题解决
