Description

In the PR discussion on HBASE-24106, elserj mentioned that another project has had success with switching its unit test suite to use RawLocalFileSystem from LocalFileSystem. This is discussed in the context of the availability of the hsync and hflush stream capabilities, which are not available on LocalFileSystem.

Perhaps we should also consider doing the same for our default standalone user experience. I don't know if doing so should be a separate task from this one, or if completing one is effectively performing the implementation for the other.
