Thanks, Fecher for your reply .

 However,  'geowave store listtypes <storename>' gives me the following output with no types.

'

05 Nov 19:40:39 WARN [core.NettyUtil] - Found Netty's native epoll transport, but not running on linux-based operating system. Using NIO instead.

05 Nov 19:40:40 WARN [core.Cluster] - You listed localhost/0:0:0:0:0:0:0:1:9042 in your contact points, but it wasn't found in the control host's system.peers at startup

Available types: 

'

The following are the steps I followed to ingest data 

1.geowave store add teststore3 -t cassandra  --contactPoints localhost --gwNamespace test3

2.geowave index add -t spatial teststore3 testindex3

3.geowave ingest localtogw sample.csv teststore3 testindex3 -f geotools-vector

Here sample.csv contains columns lat, long . I can see a keyspace 'test3' created in cassandra with one table name 'index_geowave_metadata' .But when i do Dbscan with the below command

'geowave analytic dbscan -cmi 5 -cms 10 -emn 2 -emx 6 -pmd 1000 -orc 4 -hdfs localhost:9870 -jobtracker localhost:8088 -hdfsbase /test_dir teststore3 --query.typeNames  '

 It gives me error saying 

'Expected a value after parameter --query.typeNames'

What should I do now? Can anyone say where am i going wrong?

Sorry for this long mail,I am a newbie to all these concepts .

Thankyou.

"The following option is required: --query.typeNames "

I cant find any documentation regarding this?

Thank you.

When you ingest vector (also known as feature) data, the data has a feature
type name.  This parameter is asking which type name(s) you want to apply
the analytic on. `--help` will print the option descriptions at any point
and the `geowave store listtypes <storename>` will print out the types you
currently have in your store.

Hope that helps!
