Wei-Chiu Chuang commented on HDFS-16645:
----------------------------------------
For the scenario that we observed, the older inprogress edit log files were
valid edit log files except they were not finalized. So if JN simply
delete/ignore the older inprogress files JN would abort due to the gap in
transaction id.
Example:
edits_1000_1005
edits_inprogress_1006
edits_1010_1015
edits_inprogress_1016
> Multi inProgress segments caused "Invalid log manifest"
