Problem In Running Cassandra-2.0.4 Trigger Example

I am new to cassandra and trying to run the trigger example provided by
cassandra on a pseudo cluster using instructions provided on
https://github.com/apache/cassandra/tree/cassandra-2.0/examples/triggers
But i am getting error:   *Bad Request: Key may not be empty*
Can someone tell me if my "CREATE table" is proper? What else can be wrong?
I am doing following using cqlsh.
   - CREATE KEYSPACE keyspace1 WITH REPLICATION = { 'class' :
   'SimpleStrategy', 'replication_factor' : 1 };
   - use keyspace1;
   - CREATE TABLE invertedindex ( f1 varchar , f2 varchar, f3 varchar,
   PRIMARY KEY(f1));
   - CREATE TABLE table1 ( f1 varchar , f2 varchar, f3 varchar, PRIMARY
   KEY(f1));
   - CREATE TRIGGER mytrigger ON table1 USING
   'org.apache.cassandra.triggers.InvertedIndex';
   - insert into table1 (f1,f2,f3) values ('aaa','bbb','ccc');
This is what i get in system.log:
*INFO  [Thrift:1] 2014-01-11 14:48:09,875 InvertedIndex.java:67 - loaded
property file, InvertedIndex.properties*
This is content of conf/InvertedIndex.properties file:
*keyspace=keyspace1*
*columnfamily=invertedindex*
Thanks in advance.

I'm not sure if this is your issue as I have not used these triggers before but shouldn't the invertedindex table have a different primary key than the primary table (either f2 or f3)?

My guess is the trigger is trying to create a row with an empty key. 
Add some logging to the trigger to see what it�s doing.

Hi, I am just getting started with Mahout so bear with me. I'm trying to set up the example for Taste using the instructions found here: https://cwiki.apache.org/confluence/display/MAHOUT/Recommender+Documentation (under Demo) I have tried with versions 0.7 and 0.6, and everything goes fine until I run mvn jetty:run. Then, I get this error: javax.servlet.ServletException: java.lang.

Hi Guys, 1. Before I slog my way through the documentation on using triggers? Is anyone aware of any real world usage sample code or blogs with examples on this? 2. My use case is, if an update would result in changing (for example) the the �name� field of the �person� table, storing a copy of the record in a �person_history� table. Not sure if this is trivial or even possible using triggers
Hallo, I have a cluster of four machines running hadoop-0.19.1 and hbase-0.19.3. I am interested to write a program where the map function reads from the hbase. I was able to compile and run the simple Java example MyClient from the "HBASE 0.19.3 API" document. Now I tried the example BulkImport which is very close to my need, I was able to compile it but got and error when running it. *For running
Hi all, I am having a problem running the 20 newsgroup example in a hadoop cluster. The trainclassifier worked fine but I got "out of memory java heap" problem in the testclassifier.

Hadoop: 0.20.2, HADOOP_HEAP_SIZE200 in hadoop-env.sh, mapred.child.java.opts=-Xmx1024M in mapred
Since I have problems with my application I tried running the sample- rest-java project. I had no problem running the javacount example. Since I am interesting in cassandra I tried running the persistentjavacount and I got the following exception ERR [20100414-10:54:52.190] actor: Exception when invoking ERR [20100414-10:54:52.190] actor:         actor [Actor[sample.rest.java.PersistentSimpleService
Hi, I'm starting with spark and I'm having some issues. When I run the 'jar' example of JavaDirectKafkaWordCount it works perfectly. However, if I compile the code and when I submit it, I'm having the following error: The program is running locally and the driver configuration is with 4g. Some help is always welcome, Thanks.
