I'm getting the same error message in a distributed (master/slave) configuration. The plugin works fine for me for mpeg dash in a non distributed setup.

Hello,

Thanks for reporting this bug. We have already identified the issue. As @ingoheut has mentioned, this issue is triggered when running a master/slave test.
We have already added this issue to our road map. We will be reaching back to you as soon as possible with any further updates.

Best regards,
Joaquin.

Hi Joaquin,

First at all, thank you for the plugin.
In the meantime, is there a workaround that could you share?

same issue here with HLS 3.0.2 and jmeter 5.3

Hi, any pointers to how this issue could be resolved until the fix is made available?

[Baraujo25]

Hello,

Thanks everyone for manifesting this issue. We have just released a new version of the plugin, v3.0.3. This release should have fixed this issue when running master-slave tests.

Let us know if the new version solves it.

Note: This version will be available on the Plugin Manager in a couple of days. In the meantime, the plugin can be installed manually.
Steps to install HLS-Plugin manually:

1. Download all the jar dependencies attached to the last release.
2. Copy the jar file called jmeter-bzm-hls-3.0.3.jar into JMeterHome/lib/ext/
3. Copy the leftover jars (should be nine) into the JMeterHome/lib/

Best regards,
Joaquin.

Hi @Baraujo25. I installed and tested it. 3 /lib jars (jackson-annoation, jackson-core and jackson-databind) in my installation were on a different version as compared to 3.0.3 release, so I replaced them. Rest of /lib jars were on the same version as in the release. Also, I deleted jmeter-bzm-hls-3.0.1.jar and added jmeter-bzm-hls-3.0.3.jar in /lib/ext.

It works on inital tests (y). Will keep you updated. Thanks!

Hi @waqqas-meraj-rt ,

I'm glad to hear that. Yes, some of the dependencies didn't change its version.

As an update: The plugin is now available for download on Plugin Manager

Best regards,
Joaquin.
