Start with the stack trace locations in UnstructuredStorageReaderUtil.java and HdfsReader.java, then inspect the CsvReader dependency referenced by the failure. The issue does not identify a reproducing input, expected memory behavior, or acceptance criteria, so confirm those with maintainers before proceeding. Done should include a verified resolution of the reported Java heap exhaustion.
