elassandra: Unable to run cassandra in elastic search mode due to missing path.home

Elassandra version: 6.2.3.13 and 6.2.3.12

JVM version (java -version): 1.8.0_191

OS version (uname -a if on a Unix-like system): Linux 4.4.0-142-generic #168-Ubuntu SMP Wed Jan 16 21:00:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Description of the problem including expected versus actual behavior:

Steps to reproduce: Unable to run the node in elastic search mode. If we try to run the node in sudo mode, it says elastic search node cannot run as root. If we try to run in non sudo mode, we get the following error.

We tried this in multiple systems hoping any system problem, but still unable to run the node in -e mode. Even tried adding -Des.path.home as suggested in online forums.

Hi,

Elassandra cannot run as root because Elasticsearch forbids it ! Moreover, this is not a good security practice to run cassandra as root, so run it with user cassandra.

Thanks, Vincent.

Please run it as ./cassandra -f -e in non sudo mode and paste that output. I too faced error when running in sudo mode.
