Deleting shard in solr

[Neeraj giri <gi...@gmail.com>]

Hi all,
I am trying to delete a shard in solr, but its saying shard is active and
cannot be deleted.
Is there a way to make a shard inactive ad then delete it? or any other way
to delete a shard
Regards,

Neeraj giri

After a split completes, you can delete the original shard, because at 
that point it will be inactive, and the newly created shards will cover 
its hash range.

Thanks,

Which router is the collection using?  If it's the default compositeid, 
you can't delete a shard.  If you did, the docs that matched the hash 
range for that shard would have nowhere to go.  You also can't add a 
shard with that router.  About the only thing you can do along these 
lines is SPLITSHARD.

With the implicit router, you are 100 percent in control of which shards 
get which docs, so adding and deleting shards is permitted.

Thanks,
Shawn
