Subject Re: SolrCloud Config file
Date Tue, 12 Apr 2016 00:40:44 GMT
Thanks Shawn.

Where is the path of topic collection zookeeper config file? Here is from 
wiki (see below). But I was not able to find configs/topic anywhere in the 
installation folder. 

"The create command will upload a copy of the data_driven_schema_configs 
configuration directory to ZooKeeper under /configs/mycollection. Refer to 
the Solr Start Script Reference 
<https://cwiki.apache.org/confluence/display/solr/Solr+Start+Script+Referen
ce> page for more details about the create command for creating 
collections.”



Here is the command that I run and verify zookeeper is in port 8983. BTW, 
I did not modify anything and the Solr is a clean install so I do not know 
why Python is used in the script. The error looks to me that the config 
folder was not created at first command. So when you try to update it, it 
gets an IO error.

./solr status

Found 2 Solr nodes:

If you run the following steps, you would be able to reproduce the issue 
every time.

Step 1) bin/solr start -e cloud -noprompt
Step 2) bin/solr create -c topic -d sample_techproducts_configs
Step 3) ./zkcli.sh -cmd upconfig -zkhost localhost:9983 -confname topic 
-solrhome /locm/solr-5.5.0/ -confdir 
/locm/solr-5.5.0/server/solr/configsets/sample_techproducts_configs/conf
