@parthchandra - Thanks for the feedback. IOException is thrown for various
reason from FileSystem api's and hence I was just printing the exception
message. But I have added a hint statement based on impersonation case
specifically. Now it will print like below.
Error: RESOURCE ERROR: Failed to create schema tree.
IOException: Error getting user info for current user, anonymous
_[Hint: Username is absent in connection URL or doesn't exist on Drillbit
node. Please specify a username in connection URL which is present on Drillbit
node.]_
