Titan with hbase on windows 7 configuarations

Question

I am struggling to set up titan with Hbase .Below are the stteps I followed,

1. Downloaed titan-hbase
2. downloaded cygwin
3. Installed Hbase ( referred this http://hbase.apache.org/cygwin.html)
4. Hbase in running in cygwin .
5. 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 .

Answer 1

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/.

Answer 2

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