Subject How to assign a hash range via zookeeper?
Date Thu, 04 Feb 2016 20:37:54 GMT
One of our shards went down.  We brought it back up but it doesn't have a
hash range:

<lst name="shard1">
<null name="range"/>
<str name="state">active</str>
<null name="parent"/>
<lst name="replicas">
<lst name="core_node1">
<str name="core">marketmuse_shard1_replica1</str>
<str name="base_url"></str>
<str name="node_name"></str>
<str name="state">active</str>
<lst name="core_node2">
<str name="state">active</str>
<str name="core">marketmuse_shard1_replica2</str>
<str name="node_name"></str>
<str name="base_url"></str>
<str name="leader">true</str>

This results in the error message:

org.apache.solr.common.SolrException: No active slice servicing hash code
a55b940e in DocCollection

I've been reading guides online and they suggest updating the Zookeeper

Specifically, they suggest getting clusterstate.json.  But I've tried that
and when I get that file, I only get an empty file {}

Is there another way to ask Zookeeper to cover the missing hash range?
