[jira] [Comment Edited] (SOLR-9077) Streaming expressions should support collection alias

    [ https://issues.apache.org/jira/browse/SOLR-9077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15623330#comment-15623330 ]

Looks good from a quick review, but it's a pretty big patch. It will take a little time to take the whole thing in. If you're feeling comfortable with it feel free to commit, I'm sure this code will get exercised plenty before the 6.4 release.

> Streaming expression in solr does not support collection alias
> when I tried to access collection alias I get null pointer exception 
> issue seems to be related to following code , clusterState.getActiveSlices returns null 
>  Collection<Slice> slices = clusterState.getActiveSlices(this.collection);
>  for(Slice slice : slices) {
> }
> fix seems to fairly simple , clusterState.getActiveSlices can be made aware of collection alias. I am not sure what will happen when we have large alias which has hundred of slices.
