Jun,

So, I connected to zookeeper just using telnet, and using the 4 letter
commands.

If I do a dump:

I do not see anything but valid topics, and valid consumer/owners mappings.

If I check watches, I see all the 1000's of bogus topics, e.c.:

wchc:
....
/brokers/topics/<obsolete-topic>
....

or

wchp
....
/brokers/topics/<obsolete-topic>.
0x383d6fe1b83f0008
0x383d6fe1b83f0009
0x7c3d6f9020d00041
0x833d6fe2826e0000
0x383d6fe1b83f000a
....

The kafka and zookeeper servers, as well as the consumer apps, are rolled
several times a day, automatically.

I'm not sure how to remove the watches, is that what I need to do?

Since this is a highly available system, can I bring down each zk server 1
at a time, and clear the bogus topics (or watches)?  How do I do this?
