xubo245 commented on CARBONDATA-2085:
-------------------------------------

df is select from maintable, you can ignore "sql("select * from 
maintable_agg0_minute").show(100)"

Why it fail in test case 1? but test case 2 success? 


{code:java}
checkAnswer(df,
       Seq(Row(Timestamp.valueOf("2016-02-23 01:01:00"), 120),
         Row(Timestamp.valueOf("2016-02-23 01:02:00"), 280)))
 
{code}
