503 Server Error When Indexing WikiData Using Solr

[LiuYuLOL]

Hi, I tried to deploy tapioca on a server but I meet this HTTP Error.

requests.exceptions.HTTPError: 503 Server Error: Service Unavailable for url: http://localhost:8983/solr/admin/collections?action=CREATE&name=test2_collection&collection.configName=tapioca&numShards=1

Solr is running with the status:

Found 1 Solr nodes:

Solr process 82765 running on port 8983
Picked up _JAVA_OPTIONS: -Djava.io.tmpdir=/home/uqyliu42/tmp
{
"solr_home":"/home/uqyliu42/tools/solr-7.7.2/server/solr",
"version":"7.7.2 d4c30fc2856154f2c1fefc589eb7cd070a415b94 - janhoy - 2019-05-28 23:37:48",

"memory":"218.5 MB (%5.6) of 3.8 GB",
"cloud":{
"ZooKeeper":"localhost:9983",

"collections":"1"}}

And I can create collections using bin/solr create -c <name>. Besides, the ports are available with

(base) [uqyliu42@deodar solr]$ lsof -i -P -n | grep LISTEN
java 82765 uqyliu42 48u IPv6 128497800 0t0 TCP 127.0.0.1:7983 (LISTEN)

This is an error that you can probably investigate by looking at Solr's logs, for instance via its web interface.

could u please tell how to address this error when I want to create a Solr collection?
command: "tapioca index-dump my_collection_name latest-all.json.bz2 --profile profiles/human_organization_place.json"
error: "requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: http://localhost:8983/solr/admin/collections?action=CREATE&name=col1top&collection.configName=tapioca&numShards=1"

[wetneb]

This could be because you haven't uploaded the corresponding configset before. See the end of https://opentapioca.readthedocs.io/en/latest/install.html#installing-solr. If that was indeed the problem, perhaps we could add a pointer to this section from the one where we create the collection? Let me know if that helps.

[dinani65]

I have followed the required steps according to https://opentapioca.readthedocs.io/en/latest/install.html.
Could u please explain more what I need to do?

[wetneb]

Then I don't know! Have you looked at the solr logs to understand better why this 400 error is thrown? There should be more explanations there.

[dinani65]

In order to run Solr in cloud mode, I run the following command:
service solr start -c -m 4g
but the logs shows:
org.apache.solr.common.SolrException: Solr instance is not running in SolrCloud mode.

[wetneb]

It is probable that the syntax to start solr in Cloud mode is different when you use the service command. Perhaps you could find out what is the correct way to configure Solr when starting it with the service command?
