Hi Zhang,
Thanks for your reply, I tried this but no use. It still throws up
Incompatible build versions.
I removed the dfs local directory on slave and issued start-dfs.sh on
server, and when I checked the logs it showed up with the same problem.
Do you guys need some more information from my side to have a better
understanding about the problem.
Please let me know,
Thanks
Ved
