Re: [geomesa-dev] Plan for feature updates
|
Hi Dale,
There seems to be an issue with your trusted certificates in java. What version of java are you using? Using oracle's 1.8.0_74, I can connect to the repo without issue. If you're using an older version,
it might not have the same trusted certificates installed. Java keeps this under $JDK_HOME/jre/lib/security/cacerts. You can try updating your java version, or just copying the cacerts file from
a newer java version into your existing install.
Hope that helps,
Thanks,
Emilio

Hi Dale,
We've merged the NRT FeatureEventListener changes to master for GeoMesa. To work against that immediately, you can get refresh off the Hudson 1.2.1 snapshot jars from LocationTech's Nexus.*
In terms of sample code, I updated our GeoMesa Kafka Quickstart here (1).
Under 'Prerequisites', specifically, you should 1. download Kafka 0.8.2.1 (2) 2. unzip and untar it 3. Start ZooKeeper (./bin/zookeeper-server-start.sh
config/zookeeper.properties)
4. Start Kafka (./bin/kafka-server-start.sh config/server.properties)
After completing the steps in 'Download and Build the Tutorial' and 'Run the Code', you can safely skip the all sections 'Register the Layer in GeoServer', and go to '(Optional) Listening for FeatureEvents'. This section has you run a second jar (which you'll want to run first; either that or you can re-run the first jar which produces messages).
The 'KafkaListener' clas (3) demonstrates how to connect to an NRT cache, create and add a FeatureListener. As a note about FeatureEvent types, only 'CHANGED' and 'REMOVED' are used.
Let me know what questions you have. We are starting work on the backports to GeoMesa 1.1.0-rc.5. We are planning on making those artifacts available on DI2E. Chris or I will update you once we have those up on DI2E's Nexus.
Cheers,
Jim
