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

             Summary: NullPointerException in ParallelFileMetadataLoader's load() method
                 Key: IMPALA-9907
                 URL: https://issues.apache.org/jira/browse/IMPALA-9907
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


ParallelFileMetadataLoader.loaders_ became a Map, but at one place we still treat it as a List:
{noformat}
LOG.error(logPrefix_ + " encountered an error loading data for path " + loaders_.get(i).getPartDir(), e);
{noformat}
'i' is an integer, while the loaders_'s key type is Path.

Unfortunately the code compiles which means we get a NullPointerException for this statement.
