[jira] [Created] (SPARK-7755) MetadataCache.refresh does not take into account _SUCCESS

Rowan Chattaway created SPARK-7755:
--------------------------------------

             Summary: MetadataCache.refresh does not take into account _SUCCESS
                 Key: SPARK-7755
                 URL: https://issues.apache.org/jira/browse/SPARK-7755
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Rowan Chattaway
            Priority: Minor


When you make a call to sqlc.parquetFile(path) where that path contains partially written files, then refresh will fail in strange ways when it attempts to read footer files.
I would like to adjust the file discovery to take into account the presence of _SUCCESS and therefore only attempt to ready is we have the success marker.

I have made the changes locally and it doesn't appear to have any side effects.

What are peoples thoughts about this?
