-----------------------------------------
Summary: Handle ByteBufferAllocator gracefully
Key: PARQUET-2431
URL: https://issues.apache.org/jira/browse/PARQUET-2431
Project: Parquet
Issue Type: Bug
Components: parquet-mr
Affects Versions: 1.13.1
Reporter: Gabor Szadovszky
Assignee: Gabor Szadovszky
We have introduced the interface
[ByteBufferAllocator|https://github.com/apache/parquet-mr/blob/master/parquet-common/src/main/java/org/apache/parquet/bytes/ByteBufferAllocator.java]
a while ago. This interface has its {{release}} method while parquet-mr does
not test it whether it is invoked properly in all required situations.
We need to add tests for this and fix the potential issues.
Note: In most cases the release method is a no-op so not invoking it would not
cause any issues. Meanwhile, if someone would implement their own
{{ByteBufferAllocator}} that requires the {{release}} method to be invoked we
might generate memory leaks failing to do so.
