> Key: NIFI-2873
> URL: https://issues.apache.org/jira/browse/NIFI-2873
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0
> Reporter: Franco
> Fix For: 1.1.0
>
>
> This is the same issue that previously affected Spark:
> https://github.com/Jianfeng-chs/spark/commit/9f2b2bf001262215742be418f24d5093c92ff10f
> We are experiencing this issue consistently when trying to use
> PutHiveStreaming. In theory this should be a problem with GetHDFS but for
> whatever reason it is not.
> The fix is identical namely preloading the Hadoop configuration during the
> processor setup phase. Pull request forthcoming.
