    Resolution: Not A Problem

> Allow bypassing some minor exceptions while loading editlog
> -----------------------------------------------------------
>                 Key: HDFS-8877
>                 URL: https://issues.apache.org/jira/browse/HDFS-8877
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: namenode

> 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.
