MasterNotDiscoveredException exception when running create queries in CrateDB

CrateDB

Hi Team,

I am getting exception when creating an user/table in CrateDB.

I was able to run the select quries.

Exception : MasterNotDiscoveredException[org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];]

What could be the reason, why it is blocking the create operation?

I have attached the yaml file please refer that as well.

Hi,
In this case I would look at the logs from both pods for further details, maybe you want to share those?
