Jing Zhao created HDFS-8877:
-------------------------------
Summary: 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.
