David Smiley commented on SOLR-5750:
------------------------------------
Hello Varun. I've been kicking the tires on this. When I run it explicitly,
it seems to work fine -- no errors. I also tested changing my IP address
between backup & restore, simply by switching my network connection, and I'm
glad to see the restored collection with the correct IPs.
Unfortunately, the test has never succeeded for me. Half the time I get an NPE
from Overseer, the other half the time the test fails its asserts at the end
but before then I connection failure problems that I have yet to look closer
at. The Overseer NPE is curious... clusterState.json is null causing an NPE
when a log message is printed around ~line 214, log.info("processMessage: .....
I started to debug that a bit but moved on. I plan to look further into these
things but I wanted to report this progress.
BTW I see no RestoreStatus in the patch.
I was thinking maybe I'll throw up an updated patch in ReviewBoard, but I'm
waiting on INFRA-11152

> We should have an easy way to do backups and restores in SolrCloud. The
> ReplicationHandler supports a backup command which can create snapshots of
> the index but that is too little.
> The command should be able to backup:
> # Snapshots of all indexes or indexes from the leader or the shards
> # Config set
> # Cluster state
> # Cluster properties
> # Aliases
> # Overseer work queue?
> A restore should be able to completely restore the cloud i.e. no manual steps
> required other than bringing nodes back up or setting up a new cloud cluster.
> SOLR-5340 will be a part of this issue.
