> I found several crashes like this one while looking at minidumps from a private cluster. Below is the stack of the crashing thread. I'll also attach a full resolved minidump. I suspect that this happened while Impala was scanning an Avro file while it was being overwritten. I tried to reproduce this but couldn't do so. I also suspect this could be related to IMPALA-4223.
