hi guys,
Currently, NameNode uses read-write lock at top root folder. In my
opinion, it's too huge for whole namespace with million of file/folder.
Meanwhile, a few level folder on top of the namespace directory has been
set with different application. Does we need lesser lock level for such
application sub-directory to reduce impact each other? It can be used with
five(or less) top level to HDFS path with individual lock tree-like
structure.
Can anybody provide your feedback or advice? Thanks
-Regards
