> RBF: NPE in Router concat when trg is an empty file.
> ----------------------------------------------------
>
> Key: HDFS-17462
> URL: https://issues.apache.org/jira/browse/HDFS-17462
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.10.2, 3.3.6
> Reporter: NaihaoFan
> Assignee: NaihaoFan
> Priority: Minor
> Labels: pull-request-available
>
> When trg of Router concat is an empty file, it will trigger NPE in Router,
> and the concat will fail, example:
> This is because when trg is an empty file, NameNode will return
> lastLocatedBlock as null in the response of getBlockLocations. And Router
> will not check null of lastLocatedBlock returned, instead Router will use it
> to get block pool id directly.
> Trg of concat is an empty file should be allowed in router since this case is
> supported by concat of NameNode.
