> Key: PARQUET-1533
> URL: https://issues.apache.org/jira/browse/PARQUET-1533
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: 1.11.0
> Environment: Mac OS 10.14.1
> Reporter: Xinli Shang
> Assignee: Gabor Szadovszky
> Priority: Minor

> Parquet-1485 initialize the buffer size(inputBuffer and outputBuffer) from 0
> to 128M in total. This cause the unit test TestSnappy() failed with OOM
> exception. This is on my Mac laptop.
> To solve the unit test failure, we can increase the size of -Xmx from 512m to
> 1024m like below. However, we need to evaluate whether or not the increase of
> the initial size of direct memory usage for inputBuffer and outputBuffer will
> cause real Parquet application OOM or not, if that application is not with
> big enough -Xmx size.
