pysolr.SolrError: ('Unknown collection: %s", collectionname)

[EssamEid614]

i am trying to use the pysolr api and i am getting this strange error my solr instance is in cloud mode with zookeeper running and i can even see the collection name inside the solr admin browser
can anyone help with that ?
solr version running is 5.5.3 with zookeeper 3.4.6 on ubuntu server 16.01 with anaconda 3 and python 3

I just pushed ac421dc which will at least fix that error message to show the name it expected to find. Do you know which collection name was being passed in and/or have a reproducible test case for this?

@acdha sorry for the late reply , i just modified my pysolr.py as well and it still wont find the collection , i added a line to print self.collections which prints "{}" meaning no collections exist for solr is this normal ? i am sure the collection is created i can see it on my solr admin menu and i can see all my nodes are alive
also yes i know the collection name its trying to add data to and i tried 2 different collections which i can see in my solr admin view that they exist however they still cant be seen by pysolr

You can change pysolr.ZooKeeper.CLUSTER_STATE = '/collections/{collection_name}/state.json'
according to your collection. Then it'll work. Because solr stop managing cluster states in clusterstate.json

[acdha]

That looks like a bit of a refactor since

pysolr/pysolr.py

Line 1279 in f848946

@self.zk.DataWatch(ZooKeeper.CLUSTER_STATE)

assumes that the cluster state URL can be known in advance and now it'll need to change when the collection changes.

This is still an issue for me

[acdha]

@chadgh Yes - if you want to contribute a pull request I’m sure it’d be appreciated by the other users

[chadgh]

@acdha Maybe I will.

For reference it looks like since version 6.3.0 SolrCloud doesn't update the clusterstate.json anymore.

I've got a working version of pysolr tweaked a bit after I found that out. I'll do some more testing and submit a PR.

hi @chadgh , any news on this ?

[chadgh]

@parisni, Sorry, not really.

I've made a few changes to the pysolr file to get things working with solr cloud 7.3. I have not tested it against other versions of solr and am in the middle of getting things to work for my specific problem.

I have no timeline on when I'll be able to get a solution submitted that is tested and compatible with other versions of solr.

[parisni]

@chadgh thanks for the answer.

From my side the @uzayr method worked. That's fairly simple. (solr 7.6)

@acdha I've run into this as well and would like to contribute a PR. Can you reopen and assign to me please?

Hi, I think I encountered similar issue. My specific use-case is integration testing. It looks like I have this error if I create new instance of pysolr.ZooKeeper too early (maybe service itself is not fully initialized?) For me sleep(5) solves this problem, but I hate that.

btw, @rokclimb15 how is progress?
