Konstantin Shvachko commented on HDFS-15076:
--------------------------------------------
Hey [~ayushtkn], thanks for looking. A variable will cause compilation error.
Enclosing type should use effectively final variables, therefore needs an
object.
I checked failed tests locally. All pass except {{TestRedudantBlocks}}, which
is failing without the patch as well.
> Fix tests that hold FSDirectory lock, without holding FSNamesystem lock.

> FSDirectory lock. They should also hold the global Namesystem lock.
