Titan with hbase on windows 7 configuarations - java

I am struggling to set up titan with Hbase .Below are the stteps I followed,
Downloaed titan-hbase
downloaded cygwin
Installed Hbase ( referred this http://hbase.apache.org/cygwin.html)
Hbase in running in cygwin .
5.Titan is running on my windows and basic gremlin console is coming up.
Now I want to load Hbase as storage in titan .
I am not understanding how to configure in titan so that it will map to hbase (which running in cygwin shell (command prompt).
I am trying something like this on my titan console
gremlin> TitanGraph g = TitanFactory.open('conf\titan-hbase-es.properties');
I am getting below error

Please someone help me to fix this .

Like remis said in the comments, installing on a Linux machine would reduce the compatibility issues. If you decide to give it a go this article contains the steps to get you started with Titan on HBase: http://blog.trackerbird.com/content/setting-up-titan-1-0-apache-hbase/.

I found the main issue under the cygwin is with the $(pwd) expression, change it to $(cygpath -aw $(pwd)) please.

Can someone help me get the Gremlin console working with a neo4j2 graph database?
Thanks in advance
As cybersam already mentioned the relevant part of the stacktrace is:
org.neo4j.kernel.impl.storemigration.UpgradeNotAllowedByConfigurationException: Failed to start Neo4j with an older data store version. To enable automatic upgrade, please set configuration parameter "allow_store_upgrade=true"
If you think your datastore is on same version as the libraries you're using doublecheck the classpath for duplicates. If you have two different versions it's generally non-deterministic which one is being used.

Upgrading Cassandra nodetool rebuild does not work

I have a cluster of 3 Cassandra nodes (2.0.9), and want to upgrade to 2.1.1. I have read the upgrade guide, but it has lots of steps. I thought an easier way was to terminate a node, relaunch one with Cassandra 2.1.1, and run nodetool rebuild on it. However, I got this error:
java.lang.RuntimeException: Error while rebuilding node: Stream failed

Is this because 2.0.9 and 2.1.1 are not compatible in data streaming? I checked this answer, which only says that MAJOR versions are incompatible. Is this also the case for minor versions? Thanks
Nodetool rebuild is used to bring up a new data center in an existing cluster, not for upgrading a node in a cluster: http://www.datastax.com/documentation/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html

My hadoop-env.sh is all set. Still don't know whats the problem here.. Please mention the command if there's something to check since I am pretty new with linux. Thanks
I think DataNode of your cluster is not running. Check using jps command.
Couldn't solve the error so found a workaround where I got a VM from cloud era on virtualBox and ran cloudera on it.

Setting up Titan and Cassandra - Could not instantiate storage manager class

I've set up cassandra server (Datastax community edition) and it's running fine.
My cassandra.yaml has the following settings:
seeds: "127.0.0.1"
storage_port: 7000
rpc_port: 9160
When I do this in gremlin shell:
conf = new BaseConfiguration();
conf.setProperty("storage.backend","cassandra");
conf.setProperty("storage.hostname","127.0.0.1");
conf.setProperty("storage.port",9160);
and,
g= TitanFactory.open(conf);
I get this error:

What am I doing wrong?
I faced the same issue. solution is compatible version check. I downloaded the latest version of cassandra and the error is gone.
apache-cassandra-1.2.5
titan-all-0.3.1
