errors occurred while upgrading from 0.5.2 to 0.6.1-rc

[Haitao Yao]

Hi,all
I got some errors while upgrading from 0.5.2 to 0.6.1-rc.

I deleted the znode: /storm in the zk server, and it works.

Do I have to do this to upgrade? Is there any other simpler way?

thanks.

here's the log:

A release in between 0.5.2 and 0.6.1 changed the format of how things
are stored on Zookeeper, which is why you got that error. The safest
way to upgrade is to shut everything down before upgrading ("hard
reset").

Major releases will almost always require a hard reset.
