-----------------------------------
Summary: collection parameter being handled differently when sent
as GET than when sent as POST
Key: SOLR-12849
URL: https://issues.apache.org/jira/browse/SOLR-12849
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: 7.5
Reporter: Shawn Heisey
This is a weird one.
Fired up a cloud example, server built from branch_7x code (7.6.0-SNAPSHOT)
Created four collections with the _default configset -- foo, foo2, bar, bar2.
Created four aliases, here's the contents of aliases.json:
{noformat}
{"collection":{
"b_s":"bar",
"b_m":"bar2,bar",
"f_s":"foo",
"f_m":"foo2,foo"}}
{noformat}
This curl command will fail, with "Could not find collection : b_s" as the
message:
{noformat}
curl -XPOST -s localhost:8983/solr/b_s/select -d 'q=*:*&rows=0&collection=b_s'
{noformat}
That seems like a bug, but it's not the whole story. Here's where things get
weird. The following two commands will NOT fail:
{noformat}
curl -XPOST -s localhost:8983/solr/b_m/select -d 'q=*:*&rows=0&collection=b_m'
curl -XGET -s "localhost:8983/solr/b_s/select?q=*:*&rows=0&collection=b_s"
{noformat}
The first one is very similar to the one that fails, except it uses an alias
pointing at multiple collections instead of an alias pointing at one
collection. The second is effectively identical to the command that fails,
except it's a GET rather than a POST -- the parameters are part of the URL
rather than being specified in the request body.
