Description

Usually when users hit editlog corruption like HDFS-7587, before upgrading to a new version with the bug fix, a customized jar has to be provided by developers first to bypass the exception while loading edits. The whole process is usually painful.

If we can confirm the corruption/exception is a known issue and can be ignored after upgrading to the newer version, it may be helpful to have the capability for users/developers to specify certain types/numbers of exceptions that can be bypassed while loading edits.
