在UE中编写一个test.sql，用azkaban启动，报错
18-02-2016 23:09:17 CST hivef ERROR - FAILED: ParseException line 1:0 character '' not supported here
怎么查都查不出问题
进入hive的log目录
查看hive.log发现问题

****原来是UE中的大坑，文件头自动加了不可见特殊文件头
另外，编写一个最简单的command类型job提交，直接提交就失败
Installation Failed. Error found in upload Cannot uploaded. Job doesn't have type set 'command'
后发现job描述文件中的第一行： # command.job 不能缺，很诡异
