Hi Abhishek, Thanks for the response with clarifications ! When I jumped into the logs .. May be I should provide some additional information regarding the Drill cluster before sharing more information what I found in the logs I have 6 nodes cluster where the 3 nodes are old and 3 are newly added nodes Old Nodes - dn1,dn2 and dn3 New Nodes - dn4,dn5,dn6 Whenever the query foreman is newly added nodes the error occurs , I don't find this error in any of the old nodes drillbit.log Even the user is Drill admin user I do see the above mentioned error . I verified that Drill admin has same UID and GID across all the nodes . I did check the uid is being passed while running the query
> INFO o.a.d.exec.store.SchemaTreeProvider - User Error Occurred: Failed to > create schema tree. (Error getting user info for current user, 992521597) Above error I could see in the drillbit.log files of dn4, dn5 and dn6 only I dont see any error like this on dn1,dn2 or dn3 nodes. Any thoughts why is it happening despite the same uid across all the nodes .
