Sergey Shelukhin commented on HBASE-8838:
-----------------------------------------
Why does the boolean used by test have to be in normal code (and public)? The
tests should be the only ones depending on this
> [WINDOWS] FileLink assumptions are broken under NTFS

> FileLink assumes that underlying files can be moved while there are open
> readers. Windows does not allow the file which has active readers to be moved
> unless the file is opened in shared mode. JDK6 and 7 open the file in
> exclusive mode by default, so moving the file while there are readers is not
> possible.
> Hadoop-on-windows copies the file, if it cannot perform the rename. This will
> cause duplication, and the original file not being deleted.
> This affects the unit test TestFileLink. On local mode over NTFS, reading
> from snapshot files and replication might cause issues, but I don't think it
> has any other implications on hbase+hdfs on windows.
