There's been some reports (https://issues.cloudera.org/browse/IMPALA-3991) that the latest Impala Kudu is slower yes, try the one that was released before that?

Regarding your log, I'd investigate what's going on in's tserver WARNING log around the time of that query.

Hi all : 

Error while import data from impala to kudu using sql "insert into ... select ..."

Using cloudera 5.7.1
Kudu version: 1.0
Impala-kudu version : 2.7.0-2
There are 10 nodes in our cluster, which run 3 kudu masters and 10 tablet server

We recently upgrade kudu from 0.10,  before that, I can execute this sql "insert into ... select ..."  well.
we have about 8,000,000 records in the "select table", Now, when I execute this sql,  it runs ok at the begining. but  when insert about 3,000,000 records, it reports error.

accessory is the error log.
