IBM Platform Symphony 7.1 Interim Fix 364964 Readme File
Abstract
The Platform Symphony IOP package has a Reduce task fail issue when the C++ framework and Lz4 compression are enabled.
Description
When the C++ framework is enabled, the Lz4 compression for Map output will lead the Reduce task to fail. This fix resolves the issue where Lz4 compression cannot work with the C++ framework.
This interim fix applies only to the following platform:
Linux ppc64le
