Deneche A. Hakim commented on DRILL-2253:
-----------------------------------------
running {{parquet-tools meta}} on the generated parquet file gives the
following informations:
{noformat}
creator: parquet-mr
file schema: root
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
date: OPTIONAL INT32 O:DATE R:0 D:1
row group 1: RC:600 TS:1885
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
date: INT32 SNAPPY DO:0 FPO:4 SZ:1895/1885/0.99 VC:600
ENC:PLAIN_DICTIONARY,BIT_PACKED,RLE
{noformat}
One important note is: the exception doesn't happen if the column's encoder is
PLAIN instead of PLAIN_DICTIONARY
> Vectorized Parquet reader fails to read correctly against RLE Dictionary
> encoded DATE column
