Support Video: How to list/ create/ delete collections from Ambari-Infra-Solr using APIs?

[#1]

Many a times, it is necessary for a engineer/administrator to manipulate the content of Ambari-Infra-Solr using the command line utilities. They might or might not have access to the GUI interface.

This video helps to understand the basic manipulation of:

• Listing collections and checking cluster status of Solr cloud.
• Creating new collections.
• Deleting the existing collections.

1. To check if ambari-infra-solr server instance is running on the node, run the following:

   # ps -elf | grep -i infra-solr
   # netstat -plant | grep -i 8886

2. If the cluster is Kerberized. Check for valid kerberos tickets:

   # klist -A

3. Obtain a kerberos ticket, if not present:

   # kinit -kt /etc/security/keytabs/ambari-infra-solr.service.keytab 
   $(klist -kt /etc/security/keytabs/ambari-infra-solr.service.keytab 
   |sed -n "4p"|cut -d ' ' -f7)

4. List SOLR collections:

   curl --negotiate -u : "http://$(hostname -f):8886/solr/admin/collections?action=list"

5. Create a collection:

   # curl --negotiate -u : "http://$(hostname -f):
   8886/solr/admin/collections?action=CREATE&name=<collection_name>&numShards=<number>"

6. The following are the optional Values:

   &maxShardsPerNode=<number>
   &replicationFactor=<number>

7. Delete a collection: 

   # curl --negotiate -u : "http://$(hostname -f):
   8886/solr/admin/collections?action=DELETE&name=collection"

8. Check status of the Solr Cloud cluster:

   # curl --negotiate -u : "http://$(hostname -f):
   8886/solr/admin/collections?action=clusterstatus&wt=json" | python -m json.tool

9. INDEX Keys:

   *solr_host = Host where solr instance(s) is running.
   *collection = Name of collection.
   *shard = Name of shard.
   *action = CREATE ( to add a collection(s) )
   *action = DELETE ( to delete a collection(s) )
   *action = CLUSTERSTATUS ( to get the list of available collection(s) in the Solr cloud cluster )
