Dremio startup error- No Cluster Identity found

I am getting this error while starting dremio in windows machine.

Server.log file:
Exception in thread “main” java.lang.NullPointerException: No Cluster Identity found
at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:226)
at com.dremio.dac.daemon.DremioDaemon.checkVersion(DremioDaemon.java:106)

Java HotSpot™ 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

Dremio.conf

paths: {

the local path for dremio to store data.

local: ${DREMIO_HOME}"/data"

the distributed path Dremio data including job results, downloads, uploads, etc

#dist: “pdfs://”${paths.local}"/pdfs"
}

services: {
coordinator.enabled: true,
coordinator.auto-upgrade: false,
executor.enabled: true
}

Link Tried with this option but no luck.

Any help is greatly appreciated. Thanks!!

If Dremio is failing or is interrupted during its initial startup, it might create an empty db directory missing some information, which in turn will cause next start attempts to fail.

Until we fix this behavior, you might want to check if a C:\Users\<username>\AppData\Local\Dremio\db directory is present and empty, and remove it (assuming if was your first time trying to use Dremio). You might also want to look server.out and server.log files to see if there’s some mention on why Dremio failed to start the first time.

Is there is a more formal way to post a jira ?
E.g under https://github.com/dremio/dremio-oss
or under https://issues.apache.org/jira/browse/
?

Currently we don’t have a public JIRA but github and/or this community forum would be the best way to post & contribute.
