Csaba Ringhofer commented on IMPALA-11795:
------------------------------------------
I think that this issue can happen specifically for TIMESTAMP columns:
What seems to happen is that the besides the integer types the stats for
TIMESTAMP is also stored as LongColumnStatsData:
https://github.com/apache/impala/blob/d0592c0dbf4d634cc26b2e9872a9f62af5249cdd/fe/src/main/java/org/apache/impala/catalog/ColumnStats.java#L572
but setLowAndHighValue() does not accept TIMESTAMP, only integer types:
https://github.com/apache/impala/blob/d0592c0dbf4d634cc26b2e9872a9f62af5249cdd/fe/src/main/java/org/apache/impala/catalog/ColumnStats.java#L465
> Failed to load table metadata from catalog due to EXCEPTION:Unsupported type
> encountered in setLowAndHighValue()
