Invalid cached data led to exceptions on read #472

Open JamesRTaylor opened 3 years ago

JamesRTaylor commented 3 years ago

Invalid cached data led to java.lang.ArrayIndexOutOfBoundsException and io.airlift.compress.MalformedInputException exceptions on read until Presto worker restarted. I don't have a reproducer, but I wanted to let you know that we saw this occurring. We're on 0.3.19, Presto 338, and using m5d.12xlarge worker nodes in AWS.

FYI, @shubhamtagra - we continue to run into this issue. It occurs when the cluster is overloaded. Essentially invalid files are loaded into the cache then every time a read occurs for these, the query fails.

Verified that the issue occurs with both read-through and async modes. Unfortunately I had to disable caching due to this issue.

Could you add a stack trace for the exception that you saw ?
