Subject [jira] [Commented] (HDFS-4179) BackupNode: allow reads, fix checkpointing, safeMode
Date Fri, 16 Nov 2012 20:43:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13499132#comment-13499132
] 

Todd Lipcon commented on HDFS-4179:
-----------------------------------

I was complaining that the general community doesn't seem interested in maintaining the code.
If only a single committer is interested in the code, that doesn't seem like enough justification
-- isn't that part of the reason we do code reviews? It ensures that the bus factor on the
project is greater than 1 -- if you end up winning the lottery and retiring to Hawaii, there
should be at least one other committer who thinks the BackupNode is a good idea and wants
to help maintain it.

> BackupNode should be allowed to accept read command. Needs some adjustments in checkpointing
and with safe mode.
