Huw created ORC-1357:
------------------------
Summary: Java doesn't handle missing compressionBlockSize while
C++ does.
Key: ORC-1357
URL: https://issues.apache.org/jira/browse/ORC-1357
Project: ORC
Issue Type: Bug
Components: compression
Reporter: Huw
Reader.cc (lines 59-65) handles when the postscript doesn't set
compressionBlockSize in the postscript by checking if it's set and using 256 *
1024 if it's not.
The ReaderImpl.java does no such checks (lines 744 and 826), and uses the
protobuffer "empty" value of 0 when the value is not specified.
This means that valid files (compressionBlockSize is optional after all) can't
be read by the Java implementation, but can be by the C++ implementation.
