I've noticed the same issue on Debian 10, `pg-activity` installed from deb package: ``` Traceback (most recent call last): File "/usr/bin/pg_activity", line 11, in load_entry_point('pg-activity==2.3.1', 'console_scripts', 'pg_activity')() File "/usr/lib/python3/dist-packages/pgactivity/cli.py", line...

Optimal would be supporting all variants, you can easily decide whether a block was passed with `block_given?`. And moreover adding 1.9 lambda syntax: ``` ruby rdd.map(&->(x){x*2}) ``` which is syntactic...

The project is still in its alpha stage, basically it is a only a proof of concept. We've tried using Spark API from Ruby and it works! :) Currently we...

Check broker's log for messages like this: ``` INFO Will not load MX4J, mx4j-tools.jar is not in the classpath (kafka.utils.Mx4jLoader$) ``` after modifying `build.gradle` by adding (also for same reason...

btw. the `JMX_PORT` is used just to [set java properties](https://github.com/apache/kafka/blob/5a97304170a697cb08f1c8d455d6661a37f92196/vagrant/broker.sh#L41) in kafka's shell scripts: ``` -Djava.rmi.server.hostname=$PUBLIC_ADDRESS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false ``` I've tried that, but JMX still doesn't start.

Allright without the hostname it works: ``` ./kafka-mesos.sh broker update 0..2 --jvm-options "-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=9998" ``` and then restart the brokers.

`dcos-kafka-service` is outdated and deprecated. The successor is [DC/OS Kafka](https://github.com/mesosphere/dcos-commons/tree/master/frameworks/kafka) (or at least we can call it that way, there are many other kafka versions in the [DC/OS Universe](https://universe.dcos.io)). DC/OS...

The problem was that I was running `mesos-kafka` in Docker container in `BRIDGE` mode. Then framework tries to bind to a random on Docker private net. If anyone is interested,...

@CBR09 We use marathon-lb (haproxy) for accessing apps running in Mesos cluster. But any service discovery (like mesos-dns) could be used.
