I'm having trouble configuring analytics support. I have upgraded the instance type of the access gateway and synced the configuration.

After restarting the gateway, I see log entries like:

  [2020-11-20T11:12:05+02:00] (analytics-launcher-i-0d55456c7d45d2f92) Starting presto- server

It seems the offending code has been changed in presto https://github.com/prestosql/presto/commit/e7eeeedcc9751c022ffb9df648ee5442cd421c32

My compute group / access gateway is running the latest datomic release 715.

Hi Tatu,

We are aware of the issue and it was caused by the auto-upgrade security update that installed a new version of Java on these machines. We are working to ship the updated release of Presto as quickly as we can this weekend. I will update this thread when it is out the door.

In the interim, a workaround is to log onto the gateway instance and run:

sudo yum downgrade java-11-amazon-corretto java-11-amazon-corretto-headless

This will allow the presto server to restart itself which it currently cannot do.

Thanks,
Jaret
