-------------------------------

             Summary: Do not ignore FileSystem errors and document expected behavior
                 Key: BEAM-3782
                 URL: https://issues.apache.org/jira/browse/BEAM-3782
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Udi Meiri
            Assignee: Udi Meiri


copy/rename:
 * it should be an error if the dst file exists
 * it should be an error if the src file doesn't exist

delete:
 * it should be an error if the file/dir doesn't exist

FileBasedSink.finalize_write:
 * should check (src, dst) pairs for existence:
 ** src only - regular rename
 ** dst only - skip rename
 ** both src and dst - if files don't match on metadata (checksum or size), delete dst then rename, otherwise delete src and skip rename
 ** neither exist - return error: bad state
