> Router getContentSummary rpc compute sub-directory repeatedly when a
> direactory and its ancestor directory are both mounted in the form of
> original src path.
> For example, suppose we have mount table entries below:
> /A---ns1---/A
> /A/B—ns1,ns2—/A/B
> we put a file test.txt to directory /A/B in namepsace ns1, then execute `hdfs
> dfs -count hdfs://router:8888/A`, the result is wrong, because we compute
> /A/B/test.txt repeatedly
