Bikas Saha commented on HDFS-2909:
----------------------------------
Aside from all the above I see some other issues.
Say everything is healthy and FSImage.rollEditLogs() is called.
It first calls FSEditLogs.rollLogs that actually rolls the logs.
It then calls storage.writeTransactionIdFileToStorage() which records this in
all storage dirs so that the information about the rolled edits is not lost.
However, NN could crash in after FSEditLogs.rollLogs() has completed and before
storage.writeTransactionIdFileToStorage() is called. That might leave the data
in an inconsistent state.
