Vinoth Chandar commented on HUDI-1098:
--------------------------------------
No. this is more about the actual code path, during finalize(). Tasks may have
crashed without writing the data files, and we should ensure that the
finalizing can handle data files not being present for some of the marker files
> Marker file finalizing may block on a data file that was never written
> ----------------------------------------------------------------------

> {code:java}
> // Ensure all files in delete list is actually present. This is mandatory for
> an eventually consistent FS. // Otherwise, we may miss deleting such files.
> If files are not found even after retries, fail the commit
> if (consistencyCheckEnabled) {
> // This will either ensure all files to be deleted are present.
> waitForAllFiles(jsc, groupByPartition, FileVisibility.APPEAR);
> }
> {code}
> We need to handle the case where marker file was created, but we crashed
> before the data file was created.
