IO / Disc "tear down" for elastic search

Hi @dliappis. Really informative, thank you.

I am trying to follow the recommendations:
checkout repositories:
drwxrwxr-x 16 user user 4096 Sep 9 15:25 rally-tracks
drwxrwxr-x 5 user user 4096 Sep 9 15:28 rally-eventdata-track

running command:
esrally --track-path=/add_disk/code/elasticsearch/rally-tracks/eventdata --target-hosts=

The process is got stuck on
[INFO] Preparing for race ... , logs are not updated and CPU is almost 0, kind of nothing is happening.
I am very new to the Rally and need some guidance on how to troubleshoot.

Thanks in advance.
