> 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
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Fix For: Impala 4.0
>
>
> 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.
