Github user wuchong commented on the issue:

    I think the root cause is that TUMBLE_START inherits the wrong type (`TimeIndicatorRelDataType`)
from rowtime column.  So maybe a better solution is to re-create a `RelDataType` from `optimizedPlan`'s
 rowType and `orignalPlan`'s rowType and pass into the `getConversionMapper` method. I create
a simple commit for this: https://github.com/wuchong/flink/commit/82c17ab45699f5f9beb925b156e760ebdeff79fb
  What do you think? @sunjincheng121  @fhueske 
    BTW, do we really need so many IT cases for this ?
