Subject RE: 6.6.0 getNumShards() NPE?!
Date Mon, 14 Aug 2017 15:25:27 GMT
Sure!

Any plugin that has SolrCore has the problem, a RequestHandler for example:

  public void handleRequestBody(SolrQueryRequest req, SolrQueryResponse rsp) throws Exception
{
    LOG.info("numShards: "+ core.getCoreDescriptor().getCloudDescriptor().getNumShards());
  }

2017-08-14 15:20:54.995 INFO  (qtp475266352-20) [c:logs s:shard1 r:core_node3 x:collection1_shard1_replica2]
i.o.l.h.CacheHandler numShards: null
2017-08-14 15:20:58.753 INFO  (qtp475266352-15) [c:logs s:shard1 r:core_node2 x:collection1_shard1_replica1]
i.o.l.h.CacheHandler numShards: 2
2017-08-14 15:24:43.589 INFO  (qtp475266352-237) [c:logs s:shard2 r:core_node1 x:logs_shard2_replica1]
i.o.l.h.CheckerCacheHandler numShards: 2
2017-08-14 15:24:57.446 INFO  (qtp475266352-21) [c:logs s:shard2 r:core_node4 x:logs_shard2_replica2]
i.o.l.h.CheckerCacheHandler numShards: null

The problem is very consistent.

Thanks,
Markus
