This is what I have done.

1. Turn off all your Solr nodes.

2. Ssh to one of your zookeeper machines and run Zookeeper's CLI. On
my machine, it's in /usr/lib/zookeeper/bin.

3. If you've chrooted Solr, just rmr /solr_chroot_dir.  Otherwise, use
rmr to delete these files and folders:

clusterstate.json
aliases.json
live_nodes
overseer
overseer_elect
collections

If you use a chroot jail, make it again with "create /solr_chroot_dir []"

4. Use Solr's zkCli to upload your configs again.

5. Start all your Solr nodes.

6. Create your collections again.
