Subject Deprecate BackupNode
Date Wed, 04 Dec 2013 23:06:36 GMT
It is almost an year a jira proposed deprecating backup node -
https://issues.apache.org/jira/browse/HDFS-4114.

Maintaining it adds unnecessary work. As an example, when I added support
for retry cache there were bunch of code paths related to backup node that
added unnecessary work. I do not know of anyone who is using this.

If there are no objections, I want to deprecate that code in 2.3 release
and remove it from trunk. I will start this work next week.

Regards,

Suresh
