I am trying to setup a KairosDB installation using Cassandra as backend, but I am facing the following error:

[HThriftClient.java:152] - Creating a new thrift connection to localhost(127.0.0.1):9042 ERROR [HConnectionManager.java:418] - MARK HOST AS DOWN TRIGGERED for host localhost(127.0.0.1):9042 ERROR [HConnectionManager.java:422] - Pool state on shutdown: :{localhost(127.0.0.1):9042}; IsActive?: true; Active: 1; Blocked: 0; Idle: 15; NumBeforeExhausted: 49

[HConnectionManager.java:303] - Exception: me.prettyprint.hector.api.exceptions.HectorTransportException: org.apache.thrift.transport.TTransportException: Read a negative frame size (-2080374784)! at me.prettyprint.cassandra.service.ExceptionsTranslatorImpl.translate(ExceptionsTranslatorImpl.java:39) ~[hector-core-1.1-4.jar:na]

I already checked the cassandra opened port and it is set to 9042. Also, I set start_rpc to true on cassandra.yaml file. Any idea on further troubleshooting?

  • Make sure no firewall is blocking your ports. Which IP/interface are you binding Cassandra to (`rpc_address` or `rpc_interface` in cassandra.yaml)? – Ralf May 03 '16 at 14:16
  • Using Thrift to connect to Cassandra is deprecated, and Hector hasn't processed a pull request in almost 2 years. In fact, Hector's main page even tells you not to use it anymore. Switch over to the DataStax Java driver, and you'll be a lot happier. – Aaron May 03 '16 at 14:35

What version of Cassandra are you using?

I think thrift is disabled in newer versions of Cassandra, you may enable the protocol by modifying Cassandra.yaml and restarting cassandra (or maybe by using nodetool).
