--------------------------------
Summary: pyarrow.lib.ArrowIOError: Unexpected end of stream: Page was smaller than expected
Key: ARROW-6058
URL: https://issues.apache.org/jira/browse/ARROW-6058
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 0.14.1
Reporter: Siddharth
I am reading parquet data from S3 and get ArrowIOError error.
Size of the data: 32 part files 90 MB each (3GB approx)
Number of records: Approx 100M
Code Snippet:
```
from s3fs import S3FileSystem
import pyarrow.parquet as pq
s3 = S3FileSystem()
dataset = pq.ParquetDataset("s3://location", filesystem=s3)
df = dataset.read_pandas().to_pandas()
```
Stack Trace:
```
df = dataset.read_pandas().to_pandas()
File "/root/.local/lib/python3.6/site-packages/pyarrow/parquet.py", line 1113, in read_pandas
return self.read(use_pandas_metadata=True, **kwargs)
File "/root/.local/lib/python3.6/site-packages/pyarrow/parquet.py", line 1085, in read
