It is just an issue with displaying the RF correctly. We should have it fixed in the next release. In the meantime the 'View Replication' feature should still work correctly I believe, it will just not display the RF correctly.</p> <p>Thanks for the bug report!</p> <p>-Nick </p> http://www.datastax.com/support-forums/topic/view-replication-shows-rfnan#post-6705 Thu, 27 Sep 2012 14:44:15 +0000 fredespi 6705@http://www.datastax.com/support-forums/ <p>Hi, and thanks for your answer:</p> <p>opscenter is at v2.1.2.</p> <p>There aren't any obvious errors in the log.</p> <p>Here is the output of show schema (I had to cut the solrconfig and schema or it would not post):</p> <pre><code>create keyspace collectors with placement_strategy = &#039;NetworkTopologyStrategy&#039; and strategy_options = {DC1 : 2} and durable_writes = true; use collectors; create column family solr with column_type = &#039;Standard&#039; and comparator = &#039;UTF8Type&#039; and default_validation_class = &#039;UTF8Type&#039; and key_validation_class = &#039;UTF8Type&#039; and rows_cached = 0.0 and row_cache_save_period = 0 and row_cache_keys_to_save = 2147483647 and keys_cached = 200000.0 and key_cache_save_period = 14400 and read_repair_chance = 1.0 and gc_grace = 864000 and min_compaction_threshold = 4 and max_compaction_threshold = 32 and replicate_on_write = true and row_cache_provider = &#039;SerializingCacheProvider&#039; and compaction_strategy = &#039;org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy&#039; and column_metadata = [ {column_name : &#039;_docBoost&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr__docBoost_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;_dynFld&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr__dynFld_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;created&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_created_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;language&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_language_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;rawText&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_rawText_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;solr_query&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_solr_query_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;source&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_source_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;text&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_text_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;timestamp&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_timestamp_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}, {column_name : &#039;uuid&#039;, validation_class : UTF8Type, index_name : &#039;collectors_solr_uuid_index&#039;, index_type : 1, index_options : { &#039;class_name&#039; : &#039;com.datastax.bdp.cassandra.index.solr.SolrSecondaryIndex&#039;}}];</code></pre> http://www.datastax.com/support-forums/topic/view-replication-shows-rfnan#post-6692 Wed, 26 Sep 2012 22:39:15 +0000 nickmbailey 6692@http://www.datastax.com/support-forums/ <p>fredespi,</p> <p>This is most likely just a bug in the OpsCenter display. A few questions to help us reproduce the issue:</p> <p>1) What version of OpsCenter are you on.<br /> 2) What is the output of running 'show schema &lt;keyspace&gt;;' in the cassandra-cli for your specific keyspace?<br /> 3) Are there any obvious errors in the opscenterd.log file?</p> <p>-Nick </p> http://www.datastax.com/support-forums/topic/view-replication-shows-rfnan#post-6691 Wed, 26 Sep 2012 22:07:52 +0000 fredespi 6691@http://www.datastax.com/support-forums/ <p>I have three solr nodes in the same rack. In OpsCenter when I click actions/view replication on any of the nodes the result is RF=NaN for each of them. RF is set to 2 for the keyspace and column family (solr) in question. As I am quite new to cassandra and datastax I am not sure if replication is actually working properly although it seems to be: after indexing about 13M documents in a round-robin fashion over all nodes, all nodes give approximately the same count for a *:* query through the admin interface and searching on one node also gives logging output on one other node. </p>
