Instaling CDH5.4 with kerberos security gives me the opportunity to make grants to namespaces etc, but I want to enable visibility labels as well, which seem to be disabled by default.   Cloudera documentation only tells me this feature is experimental, but not how to enable it. Apache Book shows to add the proper coprocessors, but it also mentions the proper order of the coprocessors.    As from: http://archive.cloudera.com/cdh5/cdh/5/hbase-1.0.0-cdh5.4.0/book.html#security.example.config ..I tried adding "org.apache.hadoop.hbase.security.visibility.VisibilityController" via the cloudera manager, but when reviewing the config changes, I see that the order is not correct, it's adding the Visibility Label in from of the (apparantly default AccessControler and TokenProvider, which is the incorrect order.   Any other way to enable this feature or to maintain the proper order?  ...

I have an avro input source, going through a morphline into Solr. For example the following structure:   {     "username" : "alex"     "date" : "21-08-2014"     "attachments" : [         "documents" : [               {                   "title": "test"                   "tags" : [ "a", "b", "c" ]               },               {                   "optional1" : "test2"                   "title" : "test2"               } ],         "source" : "school"     ] }   I can extract with extractAvroPath, like so:   ... { extractAvroPaths {      flatten : true      paths : {          /my_user : /username       # this works fine          /my_attachments : "/attachments[]"          /my_documents : "/attachments[]/documents[]"      }   } } .....   The problem being that /my_attachments or /my_documents now contain raw json/avro structures instead of a single field. How would I go about 'unwrapping' these fields so that they are all part of one solr document, while still retaining their context of the document they belong to?    ... View more

I'm having trouble extracting a nested structure from my avro data.   _attachment_body=[ {     "username" : "alex"     "date" : "21-08-2014"     "attachments" : [         "documents" : [               {                   "title": "test"                   "tags" : [ "a", "b", "c" ]               },               {                   "optional1" : "test2"                   "title" : "test2"               } ],         "context" : "school"     ] }   Extracting the paths with Avro:   ... { extractAvroPaths {      flatten : true      paths : {          /my_user : /username       # this works fine          # all three of these result in the same error message, with different patemeters          /my_attachments : /attachments[]          /my_documents : /attachments[]/documents[]          /my_contexts : /attachments[]/documents[]/context      }   } }   Results in the following error message: com.typesafe.config.ConfigExceptionWrongType: morph-solr.conf: 30: Cannot concatenate object or list with a non-object-or-list, ConfigString("/my_attachments") and SimpleConfigList([]) are not compatible.   Eventualy I would like to map the fields to a solr index. So if its possible to extract the nested structures, the followup question would be how to map those to a solr schema, but lets take it one step at a time 🙂 ... View more

I had an 'interesting' experience setting up cloudera search as an addition to a not to shabby hbase cluster.   Problems started when I created a collection with a trailing '/ ' , which is not allowed apparently. In hindsight I now know that this created a item in the overseer queue, which could not be processed, blocking all further requests. Showing up in the logs as the overseer being in a loop.   When I did not know this I tried a 'solrctl init', which did not work. After reading the warnings that this could mess up any previous solr state, which we didn't have, i continued using "solrctl init --force". I was a little surprised to see that the entire /hbase entry in zookeeper was wiped clean and all of hbase being in a state of panic, losing it's entire administration.   Revering back to zookeeper snapshots got my hbase back up and running, but I'm still baffled on: 1. How could this have happened? 2. If this is even a remote possibility of this command, I would recommend adding some extra red flags around the documentation recommending this option.   I'm running CDH4.5 with solr 1.1. ... View more
