Lose Solr config on zookeeper when it is restarted
sometimes when Zookeeper( single mode) is restarted it lose solr
collections. Furthermore when i manually upload it again then no state.json
is created in collection but clusterstate.json is created instead.
i use solr 5.1.0

Are all instances of Solr the same version? Mixing versions could cause
what Erick describes.

Sounds like you're somehow mixing old and new versions of the ZK state
when you restart. I have no idea how that would be happening, but...
It's consistent. If you're somehow creating collections with the new
format where state.json is kept per collection, but when you restart
you're somehow defaulting to the old format where there was one
gigantic clusterstate.json.
One deceptive thing is that with the new format, the clusterstate.json
node will exist but be empty, and underneath the collections node
there'll be a state.json for that collection.
Best,
Erick

zk is stand-alone. But i think solr node is ephimeral.

How are you starting zookeeper? Embedded within Solr? Stand-alone?
If you are starting it embedded, check the solr/zoo_data directory -
that's where Zookeeper is writing its info. If that is getting lost
somehow, you could loose your collections/etc.
