Assignee: Shuyan Zhang
> RBF: Fix duplicate results of getListing through Router.
> --------------------------------------------------------
>
> Key: HDFS-17134
> URL: https://issues.apache.org/jira/browse/HDFS-17134
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Shuyan Zhang
> Assignee: Shuyan Zhang
> Priority: Major
>
> The result of `getListing` in NameNode are sorted based on `byte[]`, while
> the Router side is based on `String`. If there are special characters in
> path, the sorting result of the router is inconsistent with the namenode.
> This may result in duplicate `getListing` results obtained by the client due
> to wrong `startAfter` parameter.
> For exemple, namenode returns [path1, path2, path3], while router returns
> [path1, path3, path2] to client. Then client will pass `startAfter` as
> `path2` at the next iteration, so it will receive `path3` again.
> We need to fix the Router code so that the order of its results is the same
> as NameNode.
