>                 URL: https://issues.apache.org/jira/browse/HADOOP-8968
>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 1.1.0
>            Reporter: Alejandro Abdelnur
>            Assignee: Alejandro Abdelnur
>             Fix For: 1.2.0
>         Attachments: HADOOP-8968.patch, HADOOP-8968.patch, HADOOP-8968.patch
> 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).
