I have been doing a research about Configuring Spark JobServer Backend (SharedDb) with Cassandra.
And I saw in the SJS documentation that they cited Cassandra as one of the Shared DBs that can be used.
Here is the documentation part:
Spark Jobserver offers a variety of options for backend storage such as:
H2/PostreSQL or other SQL Databases
Cassandra
Combination of SQL DB or Zookeeper with HDFS
But I didn't find any configuration example for this.
Would anyone have an example? Or can help me to configure it?
Edited:
I want to use Cassandra to store metadata and jobs from Spark JobServer. So, I can hit any servers through a proxy behind of these servers.
Cassandra was supported in the previous versions of Jobserver. You just needed to have Cassandra running, add correct settings to your configuration file for Jobserver: https://github.com/spark-jobserver/spark-jobserver/blob/0.8.0/job-server/src/main/resources/application.conf#L60 and specify spark.jobserver.io.JobCassandraDAO as DAO.
But Cassandra DAO was recently deprecated and removed from the project, because it was not really used and maintained by the community.
I am using hibernate 5.2.12.Final and hazelcast 3.12 for a application. I am running a hazelcast cluster. Also have hazelcast-mancenter-3.12 running to monitor the cluster and it all works great.
However I could not find anyway to see the statistics for the hibernate query cache hits from hazelcast mancenter or any other way.
So whats the best way to find out what are the query cache hits from hibernate when using hazelcast
Hazelcast Management Center doesn't gather Hibernate stats. It only collects stats from Hazelcast cluster members. For query cache, Hazelcast Hibernate integration doesn't distribute data among Hazelcast cluster members, but keeps the data in its local cache and uses Hazelcast topics to distribute events between members. So, Hazelcast cluster members don't have any data, only the Hibernate integration has in its local cache.
In your case, you can get Hibernate query cache statistics via SessionFactory.getStatistics().getSecondLevelCacheStatistics() programmatically, or via any other standard means that Hibernate provides.
We are using Cassandra 2.2.x version in production and currently we are manually triggering the repairs on each node. So we are planning to automate repairs using Cassandra Reaper. I don't see much documentation on it. Can anyone please list the steps how to configure the reaper in multi dc environment and use it?
We're currently running gridgain 6.2.1. Is there an existing upgrade guide in order to transition to apache ignite?
There is no such guide and it highly depends on what parts of GridGain you're using. All functionality that existed in 6.x was migrated to Ignite with a bit different API. So I suggest to update the version and start fixing compilation step by step.
I have a Cassandra cluster running and now I want to set up a cluster of opendaylight controller over it.
The wiki page just mentions that I need to point the opendaylight to the cassandra cluster but I am unable to figure out how.
Please provide some details about it.
There is an updated wiki page about how to setup clustering at https://wiki.opendaylight.org/view/Running_and_testing_an_OpenDaylight_Cluster.
You will need to use the karaf distribution and the helium release.
