I'm not compiling it.
I just download it from:
https://git-wip-us.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=examples/triggers/src/org/apache/cassandra/triggers/InvertedIndex.java;hb=HEAD
Save the downloaded file into a .class file and jar it.
How do I compile it ?

This is not really a Cassandra problem: it's a basic Java packaging problem.
First of all, the java source file is not what the runtime needs to
see in your jar; it needs the class file which was generated by
compiling it. That compiled class needs to be in a folder
corresponding to it's package, which I infer is
'org.apache.cassandra.triggers' from your earlier jar creation command
(obviously not the command you used to create the jar you just showed
us the dump of):
jar cvf
/etc/cassandra/triggers/org.apache.cassandra.triggers.InvertedIndex.jar
org.apache.cassandra.triggers.InvertedIndex.class
The META-INF looks fine, but that class should be listed as
org/apache/cassandfra/triggers/InvertedIndex.class
When you compile the source, does the compiler NOT put the binary in
an appropriate folder?

Correction.
It's:
unzip -l /etc/cassandra/triggers/InvertedIndex.jar
Archive: /etc/cassandra/triggers/InvertedIndex.jar
Length Date Time Name

I wonder; your jar creation looks a little off and I suspect your problem
might be the jar format which would lead to the failure to load. Could you
list the output of
$ unzip -l my.jar?

I did:
ls /etc/cassandra/triggers/
InvertedIndex.jar README.txt
But I'm not sure I'm creating the jar correctly.
I'm running:
jar cvf
/etc/cassandra/triggers/org.apache.cassandra.triggers.InvertedIndex.jar
org.apache.cassandra.triggers.InvertedIndex.class
where org.apache.cassandra.triggers.InvertedIndex.class contains the java
code on this url:
https://git-wip-us.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=examples/triggers/src/org/apache/cassandra/triggers/InvertedIndex.java;hb=HEAD
Also I tried with the name of the .class file and the .jar file as:
InvertedIndex.jar, InvertedIndex.class
and as
org.apache.cassandra.triggers.InvertedIndex.jar,
org.apache.cassandra.triggers.InvertedIndex.class

Did you put the jar into the /lib folder on the server ? I know it's a
basic question but it's the first idea to come in mind

Hi,
I'm following the tutorial at:
http://www.datastax.com/documentation/cql/3.1/cql/cql_reference/trigger_r.html
I'm using Cassandra 2.0.9 with Oracle Java (java version "1.7.0_60").
I have downloaded the example Java Class from
https://git-wip-us.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=examples/triggers/src/org/apache/cassandra/triggers/InvertedIndex.java;hb=HEAD
into a file named org.apache.cassandra.triggers.InvertedIndex.jar .
I then created a jar using:
jar cvf
/etc/cassandra/triggers/org.apache.cassandra.triggers.InvertedIndex.jar
org.apache.cassandra.triggers.InvertedIndex.class
I restarted the cassandra service.
The trigger does not exist:
cqlsh:mykeyspace> CREATE TRIGGER myTrigger ON myTable USING
'org.apache.cassandra.triggers.InvertedIndex';
Bad Request: Trigger class 'org.apache.cassandra.triggers.InvertedIndex'
doesn't exist
What am I doing wrong ?
