File be/src/exec/parquet/parquet-column-readers.cc:

http://gerrit.cloudera.org:8080/#/c/11949/9/be/src/exec/parquet/parquet-column-readers.cc@784
PS9, Line 784: bool ScalarColumnReader<TimestampValue, parquet::Type::INT64, 
true>::DecodeValues(

I see, the issue was introduced related to comment 
https://gerrit.cloudera.org/#/c/8319/17/be/src/exec/parquet-column-readers.cc@843

Maybe it would have been a better idea to leave the loop in ScalarColumnReader 
which called DecodeValue() (which was already specialized for int64 timestamps).

I am ok with the current solution, but it would be nice to remove this 
duplication in the future.
