      Description

      The last known transaction id is stored in the seen_txid file of all known directories of a NNStorage when starting a new edit segment. However, we have seen a case where it contains an id that falls in the middle of an edit segment. This was the seen_txid file in the sahred edits directory. The active namenode's local storage was containing valid looking seen_txid.
