If you use a special mount point for `/tmp`, make sure it is mounted so that you can run executables from it (check manpages for mount(8) and look at the exec/noexec flag).

Alternatively, you can choose an alternative directory by editing `dremio-env`, and adding a system property `-Djava.io.tmpdir=<directory>` to the environment variable `DREMIO_JAVA_EXTRA_OPTS`.
