facing issues with metrics API

[vamsikorada]

I pulled the latest master branch and created a standalone-jar. I also created tables as per the schema.cql file. Now, when i push the metric using carbon as input, all the 3 tables, metrics, path, segment are being populated correctly. The path API is also working properly. However, when i am trying to fetch the corresponding metrics for the paths, I am getting the following error

http://localhost:8090/metrics?path=com.graphiteData.test.metrics4.data.compressed&from=1465498000

  - type: carbon
    port: 2003

store:
  cluster: 'localhost'
  keyspace: 'metric'

Cassandra version details -

[cqlsh 5.0.1 | Cassandra 3.5 | CQL spec 3.4.0 | Native protocol v4]

Am i missing any step or using some wrong version of cassandra?

[vamsikorada]

Can someone please look into this and tell me if its a bug or am I doing something wrong? Been struck with this for past few days, tried with different versions of cassandra but no luck :( Thanks in advance.
