Hi, Can I run multiple instances of cloudera manager pointing to a different oracle database instance in the same oracle cluster with different SIDs.Say I create 3 oracle db instances (o1,o2 and o3) within the same cluster for my dev and qa instances.Is it supported?. Thanks, Nishanth

Thank you.If I am not wrong can I can also put my java code to parse the the soap message here.I am a java guy,so it seems to be easy for me.

Hi , I understood that part.But let us say i extract an xml from the hbase cell with following elements(name,city,country) and I want to index the solr .My solr schema also has fields (name,city and country).Now I need to parse the xml ,ge these fileds and index it to solr. extractHBaseCells { mappings : [ { inputColumn : "messages:name" outputField : "name" type : String source : value } { inputColumn : "messages:city" outputField : "city" type : String source : value } { inputColumn : "messages:country" outputField : "country" type : String source : value } ] } This would have been possible If was able to retrieve data from hbase in this format.But what extractHbaseCell would give me is an xml file.I am loking for a way to parse this using xquery and then assign then assign values to solr field.

Hi It did work and I am able to index the documents now. How ever when I go to solr admin page and query for the data ,I get an error message as below.I can see an increase in the number of documents indexed each time I put add a row into hbase. This is what I have done in general. 1.set up lily. 2.Insert record into hbase 3.navigate to solr admin UI and created a solr core for my collection. I tried restarting the solr service once I saw this error but still keeps getting it. error": { "msg": "no servers hosting shard: ", "code": 503 }

Hi , I am trying to register a lily indexer after creating the solr collection.I am getting the below warning once I run the command.Apparently the log says zoo keeper connection string not specified.I am using cdh 4.6 and search 1.2. Can some one help? hbase-indexer add-indexer -n trial1indexer -c indexer-config.xml -cp solr.zk=xxx:2181,yyy:2181,bbb:2181,kkk:2181,ccc:2181,ddt:2181/solr -cp solr.collection=trial1_collection LOGS: SLF4J: Class path contains multiple SLF4J bindings.

HI All, I am getting the below error now after doing some modifications.Any idea?. org.apache.hadoop.net.ConnectTimeoutException: 20000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketChannel[connection-pending remote=xx.xx.yy.zz:60020

Yes Kevin I am able to connect using the Hbase shell.I was able to create tables and insert data.

Nishan · ‎04-09-2014

Ok.Could that inetranally relate to org.apache.hadoop.hbase.MasterNotRunningException.I am seeing this now in my IDE when I run the hava client.I have also updated the jar version I am using in the baove post.ALso there is no secuirty setting in my hbase-site.xml.Just checked this.

Hi Kevin, I do not want to implement security in hbase at this point.These are the hbase dependecies I am pulling down from cloudera repo.Is that all required to connect to cdh hbase cluster from a java API. <dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase</artifactId> <version>0.94.15-cdh4.6.0</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-common</artifactId> <version>2.0.0-cdh4.6.0</version> </dependency> Can you please clarify if the secuirty check still needs to be done.Thanks for your help.None of the security tags are present in my hbase-site.xml created by cloudera manager.
