Hyukjin Kwon commented on SPARK-25723:
--------------------------------------
Please narrow down the problem and produce a self-contained reproducer if
possible. JIRA should file an issue rather than requesting investigation. I am
leaving this closed.
Please reopen this when there are sufficient reproducer and information.
Otherwise no one can reproduce and even no one's sure if it's actually fixed or
not.

> if i use dataset.show() this error will occured.
> if i use dataset.collectAsList() ,it's ok.
> I debug at follwing method,
> {color:#FF0000}*org.apache.spark.sql.execution.RDDConversions.*{color}
> {color:#FF0000}*rowToRowRdd(data: RDD[Row], outputTypes:
> Seq[DataType])*{color}
> if found , everytime , when i show {*outputTypes: Seq[DataType]*}*, it is
> different like this:*
> *at first time:*
> DoubleType
> IntegerType
> StringType
> *maby second or third time:*
> DoubleType
> StringType
> IntegerType
>
> The order of datatype(schema) is wrong， so when it execute
> {mutableRow(i) = converters(i)(r(i))}
> will get a wrong converter , and scala's matcherror will occured..
