Yandex-Tank unable to run JMeter - Unable to access to JMeter executable file or it does not exist

Question

I'm trying to start JMeter from Yandex.Tank in Yandex Cloud instance, based on Ubuntu 18.
Installed JMeter here: /home/tank/apache-jmeter-5.2.1/bin/jmeter
If I run JMeter using this path it starts successfully:
/home/tank/apache-jmeter-5.2.1/bin/jmeter -n -t ReloadTest.jmx -l result-1.jtl -e -o ./result-1

When I run yandex-tank, there is an error message:

[ERROR] Test interrupted:
<type 'exceptions.RuntimeError'>: Unable to access to JMeter executable file or it does not exist: 
/home/tank/apache-jmeter-5.2.1/bin/jmeter

load.yaml:

phantom:
  enabled: false
jmeter:
  enabled: true
  jmx: ReloadTest.jmx
  buffered_seconds: 10
  jmeter_path: /home/tank/apache-jmeter-5.2.1/bin/jmeter
  jmeter_ver: 5.2
  ext_log: all
overload:
  enabled: true
  package: yandextank.plugins.DataUploader
  token_file: "token.txt"

Tried this, without success:

chmod +x /home/tank/apache-jmeter-5.2.1/bin/jmeter
chmod 777 /home/tank/apache-jmeter-5.2.1/bin/jmeter

I cannot reproduce your issue using latest YandexTank 1.12.8.1, you might want to update your current installation using pip like:

pip install https://api.github.com/repos/yandex/yandex-tank/tarball/master

If will still be experiencing problems - run YandexTank with -v command-line argument, it should produce more verbose debug messages so you will be able to figure out where the problem lives

You can also try to change the ownership of the whole JMeter folder to the tank user like:

chown -R tank /home/tank/apache-jmeter-5.2.1

And finally, you can consider switching to Taurus tool which better supports JMeter and is capable of automatically downloading JMeter with plugins so you won't have to worry about installing JMeter. Check out Navigating your First Steps Using Taurus article for more details.
