FileNotFoundException with Titan (titan-all) - groovy

Question

I'm trying to set up a basic Titan example. In following the docs, I tried running bin/gremlin-server.sh -i com.thinkaurelius.titan titan-all 1.0.0 which throws;
Could not install the dependency: java.io.FileNotFoundException: /usr/share/titan/ext/titan-all/plugin/titan-all-1.0.0.jar (No such file or directory)

I also tried it from gremlin.sh;

I've confirmed that groovy has the file;
root#ubuntu:/usr/share/titan# ls ~/.groovy/grapes/com.thinkaurelius.titan/titan-all/jars
titan-all-1.0.0.jar
So now I'm stumped.. Has anyone come across this before?
EDIT: Some notes on how I got here..
My first attempt at getting this working was to use the all-inclusive zip file as per the docs... I changed gremlin-server.yaml to;
graph: conf/titan-cassandra-es.properties
That threw;
407 [main] WARN org.apache.tinkerpop.gremlin.server.GremlinServer - Graph [graph] configured at [conf/titan-cassandra-es.properties] could not be instantiated and will not be available in Gremlin Server. GraphFactory message: Configuration must contain a valid 'gremlin.graph' setting
java.lang.RuntimeException: Configuration must contain a valid 'gremlin.graph' setting
Ok, simple google search tells me I need to add this to conf/titan-cassandra-es.properties;
gremlin.graph=com.thinkaurelius.titan.core.TitanFactory
At which point, I get..
484 [main] WARN org.apache.tinkerpop.gremlin.server.GremlinServer - Graph [graph] configured at [conf/titan-cassandra-es.properties] could not be instantiated and will not be available in Gremlin Server. GraphFactory message: GraphFactory could not instantiate this Graph implementation [class com.thinkaurelius.titan.core.TitanFactory]
java.lang.RuntimeException: GraphFactory could not instantiate this Graph implementation [class com.thinkaurelius.titan.core.TitanFactory]
This leads me to believe that I'm missing com.thinkaurelius.titan.core.TitanFactory. Which is curious, since $TITAN_HOME/lib does in fact contain titan-all-1.0.0.jar. So I assumed (perhaps wrongly) that I need to run the titan-all install to make it actually load the jars..

Answer 1

The basic install for Titan is unzip the titan-1.0.0-hadoop1.zip. That is it!
Download it from http://titandb.io
http://s3.thinkaurelius.com/docs/titan/1.0.0/getting-started.html
It is already packaged with the Titan plugins, so you don't need to install them into the Gremlin Console or Gremlin Server.
If you want to try the Titan Server, there is a pre-packaged titan.sh script which automatically starts Cassandra and Elasticsearch with the server.

Answer 2

For anyone that comes across this strangeness, read the whole stack trace. It turns out waaay at the bottom, it actually had the real issue; it couldn't connect to Cassandra because I had not enabled Thrift.
