Description

Due to synchronization introduced in HDFS-4025, a journal might have an edit log and an in progress edit log with the same start tx id. This would create an exception if GetJournalEditServlet tries to download edit with that start tx id from FileJournalManager. JournalNodeSyncer can fail when trying to fetch an edit log in this scenario.

FileJournalManager#getLogFile should ignore in progress edit logs for JN sync downloads.
