> || columnType.equalsIgnoreCase("smallint") ||
> columnType.equalsIgnoreCase("int")
> || columnType.equalsIgnoreCase("bigint")) {
> LongColumnStatsDataInspector longStats = new
> LongColumnStatsDataInspector(); {code}
> IMO, Hive column does not support long data type. We should remove the
> incorrect data type in ColumnStatsUpdateTask.
>
> In addition, the column stats related code blocks should be consistent with
> code in StatObjectConverter.java, which also does not have long type.
