Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
Description: Fix copper failures by adding MPI_Finalize call and also close the dataset and file in case of failure prior to exiting.
Description: Preliminary test of H5Fflush to verify that it still works when using MPIO collective mode. Platforms: Linux (heping)
