Please refer to the Configuring the Open File Limit of the documentation here.

You don't need to start DC as root. But you were typing /bin/streamsets dc -- in fact, if you're in the main Data Collector directory, you'd just type something like ./bin/streamsets dc (a relative path, not the absolute path you were using). In Ubuntu, you'll need to edit /etc/security/limits.conf and add two lines, something like:

* soft nofiles 32768

* hard nofiles 32768

To make this take effect for your current session, run ulimit -n 32768

I am using a company mac , where I am not given a sudo access. Is there any workaround to increase the limits without being a sudo.

Before starting streamsets use "ulimit -n 32768" . It will fix the issue

Also, you can try StreamSets Data Collector with Docker. If interested, check out Getting Started with StreamSets Data Collector on Docker.

I'm trying to start the streamsets-dc docker container, but the container is exiting on start-up. Here's what I see when I run docker ps -a:

18:06 $ docker ps -a

You can see that the streamsets-dc container exits immediately on start-up. If I run the docker logs streamsets-dc command, I get the following

Java 1.8 detected; adding $SDC_JAVA8_OPTS of "-XX:+UseConcMarkSweepGC -XX:+UseParNewGC -Djdk.nio.maxCachedBufferSize=262144" to $SDC_JAVA_OPTS
Configuration of maximum open file limit is too low: 1024 (expected at least 32768). Please consult

I have to admit I'm not all that familiar with docker, but I would have assumed that the streamsets-dc container would have everything configured to just run out of the box.

Can anyone suggest what I need to do to get the container to run?

Hi Paul - you've posted this as an answer to another question. Could post it as a new question? That way more people will see it.
