Write a test.sql in UE, start it with azkaban, and report an error.

18-02-2016 23:09:17 CST hivef ERROR - FAILED: ParseException line 1:0 character '' not supported here

No matter how hard I tried, I couldn't find anything wrong.

Go to Hive's log directory

Check hive.log for problems

**** It turns out to be a big pit in UE, and the file header is automatically added with invisible special file header.

In addition, write the simplest command type job submission, direct submission will fail

Installation Failed. Error found in upload Cannot uploaded. Job doesn't have type set 'command'

Then I found the first line in the job description file: #command.job cannot be missing, very strange
