-----------------------------------
[~elgoiri] somehow there is no further comment from Hadoop QA about the build.
[~csun] helped me to trigger this build:

> RBF: RouterRpcServer getListing cannot list large dirs correctly
> ----------------------------------------------------------------

> Key: HDFS-15196
> URL: https://issues.apache.org/jira/browse/HDFS-15196
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Fengnan Li
> Assignee: Fengnan Li
> Priority: Critical
> Attachments: HDFS-15196.001.patch, HDFS-15196.002.patch,
> HDFS-15196.003.patch, HDFS-15196.003.patch, HDFS-15196.004.patch,

>
>
> In RouterRpcServer, getListing function is handled as two parts:
> # Union all partial listings from destination ns + paths
> # Append mount points for the dir to be listed
> In the case of large dir which is bigger than DFSConfigKeys.DFS_LIST_LIMIT
> (with default value 1k), the batch listing will be used and the startAfter
> will be used to define the boundary of each batch listing. However, step 2
> here will add existing mount points, which will mess up with the boundary of
> the batch, thus making the next batch startAfter wrong.
> The fix is just to append the mount points when there is no more batch query
> necessary.
