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

             Summary: Marker file finalizing may block on a data file that was never written
                 Key: HUDI-1098
                 URL: https://issues.apache.org/jira/browse/HUDI-1098
             Project: Apache Hudi
          Issue Type: Bug
          Components: Writer Core
            Reporter: Vinoth Chandar
             Fix For: 0.6.0


{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.
