Alexey Serbin commented on KUDU-3518:
-------------------------------------
[~MadBeeDo],
Could you check the logs of the impalad server that was serving that scan
request? Most likely, you'd see more information on the error. It would be
great if you could share the related snippets from those logs here.
Thanks!
