Query it with: > SELECT * from `local`.`root`.`int_16.parquet`; > The result, in the web UI, is this error: > org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: > UnsupportedOperationException: unsupported type: INT32 INT_16 Fragment 0:0 > [Error Id: c63f66b4-e5a9-4a35-9ceb-546b74645dd4 on 172.30.1.28:31010] > The INT_16 logical (or "original") type simply tells consumers of the file > that the data is actually a 16-bit signed int. Presumably, this should tell > Drill to use the SmallIntVector (or NullableSmallIntVector) class for > storage. Without supporting this annotation, even 16-bit integers must be > stored as 32-bits within Drill. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
