tongshiquan updated HDFS-8581:
------------------------------
Description:
If one directory such as "/result" exists about 200000 files, then when execute
"hdfs dfs -count /", the result will go wrong. For all directories whose name
after "/result", file num will not be included.
My cluster see as below, "/result_1433858936" is the directory exist huge
files, and files in "/sparkJobHistory", "/tmp", "/user" are not included
