I installed DataStax on Ubuntu server (VPS) and I did that step by step according to DataStax's documentations and I enabled (activated) Solr as stated by DataStax's documentations.
I created the keyspace used this query:
create KEYSPACE IF NOT EXISTS "test_db" WITH replication =
{'class':'NetworkTopologyStrategy', 'Solr':1};
I can Start the CQL interactive terminal (cqlsh) but when I run a query (common CQL in Cassandra) it returns error:
Traceback (most recent call last): File "/usr/bin/cqlsh", line 1124, in perform_simple_statement rows = self.session.execute(statement, trace=self.tracing_enabled) File "/usr/share/dse/cassandra/lib/cassandra-driver-internal-only-2.7.2.zip/cassandra-driver-2.7.2/cassandra/cluster.py", line 1602, in execute result = future.result() File "/usr/share/dse/cassandra/lib/cassandra-driver-internal-only-2.7.2.zip/cassandra-driver-2.7.2/cassandra/cluster.py", line 3347, in result raise self._final_exception Unavailable: code=1000 [Unavailable exception] message="Cannot achieve consistency level ONE" info={'required_replicas': 1, 'alive_replicas': 0, 'consistency': 'ONE'}
If anyone knows the answer of the problem, please guide me
Note: It do not want to have distributed system, and we just have this server for our development and we just want to use it during our development.
Update
This is the latest error that we see in output.log
ERROR 20:45:32,468 Fatal exception during initialization org.apache.cassandra.exceptions.ConfigurationException: Cannot start node if snitch's data center (Solr) differs from previous data center (Cassandra). Please fix the snitch configuration, decommission and rebootstrap this node or use the flag -Dcassandra.ignore_dc=true.
And we also ran dse cassandra -Dcassandra.ignore_dc=true according to the error above, but it was not effective and I still have problem!
