> // 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);

> We need to handle the case where marker file was created, but we crashed before the data file was created.
