Date Mon, 31 Oct 2016 17:02:58 GMT

     [ https://issues.apache.org/jira/browse/SOLR-9077?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kevin Risden updated SOLR-9077:
-------------------------------
    Attachment: SOLR-9077.patch

First pass at trying to make aliases work. There are no tests yet but existing tests pass.
This is an approach of refactoring getting slices.

> 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.
