-----------------------------------------

             Summary: No support reading columns of type decimal(19,4)
                 Key: ARROW-1398
                 URL: https://issues.apache.org/jira/browse/ARROW-1398
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.6.0
         Environment: Ubuntu 16.04, Python 3.6
            Reporter: Ludwik Bielczynski


I have a localy saved parquet database created in spark from querrying an SQL database. When I run:

{code:python}
import pyarrow.parquet as pq

path = "path/to/parquet/dataset"
dataset = pq.ParquetDataset(path)
dataset.read()
{code}

an error indicating that there is no support for reading columns of type decimal(19,4). It's quite a common type used in SQL databases and I saw in the source code that there is an implementation for decimals. I'm stuck trying to figuring out a solution. Is there a walk around (conversion of decimals to integers during reading)?
