Description

M5 and C5 instances use a different hypervisor than M4 and C4. In EC2 C5 and M5 instances, data loading fails. An interesting snippet from the end of an impalad log:

To reproduce this, start a M5.4xlarge with 250GB space

sudo apt-get update
sudo apt-get install --yes git
git init ~/Impala
pushd ~/Impala
git fetch https://github.com/apache/impala master
git checkout FETCH_HEAD
./bin/bootstrap_development.sh | tee -a $(mktemp -p ~)

You might need to fiddle with the default security group; I'm not sure. You can test on an M4.4xlarge, since the above script should work there.
