I'm executing a streaming expr and get this error: Caused by: org.apache.solr.common.SolrException: Could not load collection from ZK: MovieLens_Ratings_f2e6f8b0_3199_11e7_b8ab_0242ac110002 at org.apache.solr.common.cloud.ZkStateReader.getCollectionLive(ZkStateReader.java:1098) at org.apache.solr.common.cloud.ZkStateReader$LazyCollectionRef.get(ZkStateReader.java:638) at org.apache.solr.client.solrj.impl.CloudSolrClient.getDocCollection(CloudSolrClient.java:1482) at org.apache.solr.client.solrj.impl.CloudSolrClient.requestWithRetryOnStaleState(CloudSolrClient.java:1092) at org.apache.solr.client.solrj.impl.CloudSolrClient.request(CloudSolrClient.java:1057) at org.apache.solr.client.solrj.io.stream.FacetStream.open(FacetStream.java:356) ... 38 more Caused by: org.apache.zookeeper.KeeperException$SessionExpiredException: KeeperErrorCode = Session expired for /collections/MovieLens_Ratings_f2e6f8b0_3199_11e7_b8ab_0242ac110002/state.json at org.apache.zookeeper.KeeperException.create(KeeperException.java:127) at org.apache.zookeeper.KeeperException.create(KeeperException.java:51) at org.apache.zookeeper.ZooKeeper.getData(ZooKeeper.java:1155) at org.apache.solr.common.cloud.SolrZkClient$7.execute(SolrZkClient.java:356) at org.apache.solr.common.cloud.SolrZkClient$7.execute(SolrZkClient.java:353) at org.apache.solr.common.cloud.ZkCmdExecutor.retryOperation(ZkCmdExecutor.java:60) at org.apache.solr.common.cloud.SolrZkClient.getData(SolrZkClient.java:353) at org.apache.solr.common.cloud.ZkStateReader.fetchCollectionState(ZkStateReader.java:1110) at org.apache.solr.common.cloud.ZkStateReader.getCollectionLive(ZkStateReader.java:1096) ... 43 more
