Jing Zhao commented on HDFS-8877:
---------------------------------
[~cnauroth] just pointed me to the existing "recovery mode" functionality.
Actually the recovery mode should be able to solve a lot of cases we hit here.
I will close the jira by now.
> 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
> Reporter: Jing Zhao
> Assignee: Jing Zhao
>
> 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.
