Subject [jira] [Commented] (HADOOP-8968) add flag to disable completely version check in the TaskTracker and DataNode
Date Thu, 25 Oct 2012 22:03:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13484527#comment-13484527

Alejandro Abdelnur commented on HADOOP-8968:
--------------------------------------------

@Eli, you are right on buildversion matching and version not and so on. This was introduced
by HADOOP-8209. I think that should be fixed. But it is different from the issue this JIRA
is trying to solve, to allow different versions of the JT/TT DN/NN to work in order to enable
a rolling upgrade between 2 different versions, yet compatible.

> The current logic in the TaskTracker and the DataNode to allow a relax version check
with the JobTracker and NameNode works only if the versions of Hadoop are exactly the same.
> We should add a switch to disable version checking completely, to enable rolling upgrades
between compatible versions (typically patch versions).
