Issues starting up Titan embedded with cassandra + elastic search remote

[Brian]

I've followed the instructions to set https://github.com/thinkaurelius/titan/wiki/Using-Elastic-Search and verified I can access my elasticsearch node from my cassandra node, yet I still get the following error when I start titan:

my properties file:

storage.backend=embeddedcassandra
storage.cassandra-config-dir=file:///etc/cassandra/cassandra.yaml

storage.index.search.backend=elasticsearch
storage.index.search.client-only=true
storage.index.search.local-mode=false
storage.index.search.hostname=33.33.33.36,

Anyone have any ideas I can try out?

Thanks,
Brian

You should post your configuration files.

I ended up fixing the issue by overriding the default value, 0.0.0.0, for network.host in elasticsearch.yml with the private network ip address for that node (I'm testing a cluster setup via Vagrant).

Hi Can,

Please share the config file and changes done for the same as I'm facing the same issue.
