Hi [~hemanthboyina], [~fishywang] have similar suggestions in HDFS-14756, I found the usage
of \{{startsWith()}} affects different logics independently, I think changing these logics
together is not a good idea. For example, If we introduce some bugs into one of these logics
by this patch and we have to revert the commit, we must revert all the fix together.

of \{{String.startsWith()}} to identify parent path
