    Description

      In HDFS-5080, we added the ability to fetch the in-progress edit log from JournalNodes. However, in some cases, BootstrapStandby can now fetch entries that have not made it to a quorum of nodes, since we used lastWrittenTxid rather than the last committed txid. We should fix this race condition.
