Hi Modassar,
I ran into the same issue (Solr 4.8.1) with an existing collection set
to "implicit" routing but with no "router.field" defined. I managed to
set the "router.field" by modifying /clusterstate.json and pushing it
back to Zookeeper. For instance, I use field "shard_name" for routing.
Now, in my /clusterstate.json, I have:
"router":{
"name":"implicit",
"field":"shard_name"
}
Warning: you'll probably need to reload your collection (see Collection
API) for the change to be taken into account. Or a more brutal way,
restart your Solr nodes. Then you should see the update in
http://localhost:8983/solr/admin/collections?action=clusterstatus.
I'd be curious to know if there's a cleaner method though, rather than
modifying /clusterstate.json.
Otherwise, if you want to create a collection from scratch with implict
routing and a router.field (see Collection API), use:
http://localhost:8983/solr/admin/collections?action=CREATE&name=my_collection&router.name=implicit&router.field=shard_name
Good luck,
Damien
