Andrzej Bialecki commented on SOLR-13245:
------------------------------------------
There's a typo in the status message (Deamon instead of Daemon).
Also, IMHO it would be better to return a structured response instead of a
single string, eg. something like:
{code}
{
"result-set":{
"docs":[{
"DaemonOp":"started",
"name":"testD1",
"core":"gettingstarted_shard2_replica_n6"}
,{
"EOF":true}]}}
{code}
> Status checking of streaming "daemon"-s is buggy and misleading

> Key: SOLR-13245
> URL: https://issues.apache.org/jira/browse/SOLR-13245
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: streaming expressions
> Affects Versions: 7.7, 8.0, master (9.0)
> Reporter: Andrzej Bialecki
> Priority: Major
>
> When a {{daemon}} is started Solr randomly picks a replica to process that
> request and then it executes in the context of that particular replica. The
> response from the request mentions this specifically:
> {code:java}
> {
> "result-set":{
> "docs":[{
> "DaemonOp":"Deamon:testD1 started on
> gettingstarted_shard2_replica_n6"}
> ,{
> "EOF":true}]}}
> {code}
> Subsequent requests to {{/solr/gettingstarted/stream?action=list}} only
> sometimes return the status of this daemon, specifically only when the
> request is randomly routed to the actual replica that the daemon is running
> on - in other cases the response doesn't show the running daemon.
> This is very easy to reproduce using the {{cloud}} example with 2 (local)
> nodes and a source collection with multiple shards and multiple replicas.
> Currently the only workaround is to request the status using a non-cloud core
> URL - in this case a request to
> {{/solr/gettingstarted_shard2_replica_n6/stream?action=list}} always returns
> correct status.
