----------------------------------------
Summary: NPE trying to set autoscaling policy for existing
collection
Key: SOLR-13252
URL: https://issues.apache.org/jira/browse/SOLR-13252
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: AutoScaling
Affects Versions: master (9.0)
Reporter: Andrzej Bialecki
Steps to reproduce:
* create a collection without collection-specific policy, eg. {{test}}
* define a collection-specific policy {{policy1}}:
{code}
POST http://localhost:8983/solr/admin/autoscaling
{
"set-policy":
{
"policy1" :[
{"replica": "<2", "shard": "#EACH", "node": "#ANY"}
]
}
}
{code}
* try to modify the collection to use this policy
{code}
http://localhost:8983/solr/admin/collections?action=MODIFYCOLLECTION&collection=test&policy=policy1
{code}
A NullPointerException is thrown due to the previous value of the "policy"
property being absent:
