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?
