Hello,

I have the following error when starting the Dremio service:

[main] ERROR ROOT - Dremio is exiting. Failure while starting services.

        Suppressed: java.lang.IllegalStateException: #start was not invoked, so metadataManager is not available

I already identified that it is because the /tmp directory has the noexec option active and it should be for security reasons.

My question is: Where can I change the destination of these temporary files?

I didn’t find any information in the documentation.

@Jduarte1081 In your dremio-env file, add the below

DREMIO_JAVA_EXTRA_OPTS="-Djava.io.tmpdir=/path/to/tmp"

It’s works, thank you @balaji.ramaswamy !!
