> There's a case in my company: when two namenodes tried to transit state, checkpoint took
place in standbynode and it didn't check cancellation until every after 4096 inodes saved,
which took too much time between checks in our case and caused state transition fail at the
end. After we changed it to 50, state transition succeed.
> The *CHECK_CANCEL_INTERVAL* in *FSImageFormat.Saver* was introduced in HDFS-7097 and
set to 4096, previously was 50. There may be some reasons for the choice of 4096, but i'm
not sure that, so I suggest to make it configurable.
