Warning message when trying to insert data in Kudu table

New Contributor



We have a Kudu installation with 3 tablet servers and when we made some upserts from one Kudu table updating another Kudu table. We are finding these warning in all three tablet servers:

Could you let me your kudu and impala version ?

Impala Shell v2.8.0-cdh5.11.1


kudu 1.4.0-cdh5.12.0

Those warnings are likely harmless. Is there any actual failure during the upserts?
