> Found this small bug while testing multiple NNs under failure conditions on the 1073
branch. When the 2NN calls getEditLogManifest(), it expects a list of finalized logs. In the
case that one of the edit log directories had failed and recovered, there would be some txid
for which there was an edit_N_inprogress and an edits_N-M (finalized). The edit log manifest
needs to see the finalized one when it exists.
