cassandra's Issues

Add SSL support

As a user, I'm trying to integrate the cassandra-sink against an SSL secured Cassandra cluster; however, I'm getting the following error and the app eventually crashes in PCF.

Error:

OUT Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'session' defined in org.springframework.cloud.stream.app.cassandra.lemCassandraConfiguration: Invocation of init method failed; nested exception is com.datasta
x.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /<HOST>:9042 (com.datastax.driver.core.exceptions.TransportException: [/<HOST>:9042] Channel has been closed), /<HOST>:9042 (com.datastax.driver.core.exceptions.TransportException: [/<HOST>:9042] Channel has been closed), /<HOST>:9042 (com.datastax.driver.core.exceptions.TransportException: [/<HOST>:9042] Channel has been closed), /<HOST>:9042, /<HOST>:9042, /<HOST>:9042 [only showing errors of first 3 hosts, use getErrors() for more details])

Notes:
It appears that the traffic between the driver and Cassandra needs to be secured via SSL as well and we will have to provide the compatibility with the existing app.

Acceptance:

  • Expose a new property (maybe: "enableSSL=true/false") to enable SSL
  • Add trustStore and trustStorePassword as overriddable properties
  • Add unit tests

Stream pipeline silently fails to write

Hello, I am trying to follow the tutorial for deploying a stream pipeline to docker that has a simple HTTP source and sinks to Cassandra, but having trouble debugging.

Everything seems setup correctly, as far as I can tell:

I have my stream pipeline setup and deployed, and there are no error messages.

Currently the source is setup correctly and receives HTTP requests:

  • The kafka topics list:
=> docker exec dataflow-kafka kafka-topics --zookeeper zookeeper:2181 --list
__confluent.support.metrics
__consumer_offsets
cassandrastream.http
  • Sample HTTP request:
dataflow:>http post --contentType 'application/json' --data '{"isbn": "1599869772", "title": "The Art of War", "author": "Sun Tzu"}' --target http://localhost:20000
> POST (application/json) http://localhost:20000 {"isbn": "1599869772", "title": "The Art of War", "author": "Sun Tzu"}
> 202 ACCEPTED
  • Output in Kafka consumer:
=> docker exec dataflow-kafka kafka-console-consumer --bootstrap-server localhost:9092 --topic cassandrastream.http
{"isbn": "1599869772", "title": "The Art of War", "author": "Sun Tzu"}

However, nothing gets written to Cassandra

What I tried to debug:

  • I checked the cassandra sink app logs, but nothing out of the ordinary is shown in either STDOUT or STDERR besides possibly this warning:

    WARNING: An illegal reflective access operation has occurred
    WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (jar:file:/home/cnb/.m2/repository/org/springframework/cloud/stream/app/cassandra-sink-kafka/3.0.2/cassandra-sink-kafka-3.0.2.jar!/BOOT-INF/lib/groovy-2.5.7-indy.jar!/) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int)
    WARNING: Please consider reporting this to the maintainers of org.codehaus.groovy.vmplugin.v7.Java7$1
    WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
    WARNING: All illegal access operations will be denied in a future release

  • I checked the cassandra docker container logs, and nothing is shown there

  • I turned on query tracing in a cqlsh session, and no queries are recorded coming in to do the inserts.

Any guesses on what is going wrong? And any guesses on where I should look in the future to debug cassandra sink issues?

(note: I also asked more generally about how to debug SCDF sinks in this SO post, but here in this Github issue, I am asking more specifically how to debug this particular Cassandra app starter).

Cassandra sink insert query regexp validation

From @akosratku on May 14, 2016 14:27

Hi!

I would like to update counters in cassandra but the current query validation won't let me. My query looks like this:

UPDATE views SET view_count = view_count + 1 WHERE id = :id

Since it doesn't match the pattern my sink won't start up.

Is there a way to loosen the restrictions on the query? I am wondering if the pattern check is even necessary at all?!

Edit: Since cassandra already accepts queryType, the quey parsing could be based on that.

Edit2: I made a quick fix for it so I can progress, I could make it a PR and finalize it if you are interested. Compare

Regards,
Ákos

Cassandra sink's --initScript option is not working

From @sabbyanandan on May 6, 2016 17:8

From @sabbyanandan on December 16, 2015 0:1

As a user, I'm creating a stream [on local SPI] with --initScript option to create the table for the cassandra sink; however, I'm unable to get the table created successfully.

stream:

stream create cassandraTest --definition "http | cassandra --initScript=file:<absolut-path-to>/int-db.cql --ingestQuery='insert into book (isbn, title, author) values (uuid(), ?, ?)'" --deploy

data:

dataflow:>http post --contentType 'application/json' --data "{\"title\": \"Test\", \"author\": \"Sabby\"}" --target http://localhost:16784/messages
POST (application/json;charset=UTF-8) http://localhost:16784/messages {"title": "Test", "author": "Sabby"}
202 ACCEPTED

Validate combinations of options used for Cassandra Sink

From @sabbyanandan on May 6, 2016 17:7

From @trisberg on December 4, 2015 15:3

Some option combinations are not valid, like schemaOption is only valid when entityBasePackages are defined. We should try to validate that the combinations specified are valid.
