Sanjay Radia commented on HDFS-1580:
------------------------------------
Finalizing the edits at initialization makes sense. It would require reading the
edits but this should not be bad if we roll the edits at reasonable intervals.
One possibility is for this to be part of init() that returns the highest txId.
Jitendra had mentioned to me why he preferred the getNumTransaction(sinceTx)
but I forget the
reason.
