------------------------------
Summary: ORC MemoryManager thread checks are fatal, should WARN
Key: HIVE-13163
URL: https://issues.apache.org/jira/browse/HIVE-13163
Project: Hive
Issue Type: Bug
Components: ORC
Affects Versions: 2.0.0, 2.1.0
Reporter: Gopal V
Assignee: Gopal V
The MemoryManager is tied to a WriterOptions on create, which can occur in a
different thread from the writer calls.
This is unexpected, but safe and needs a warning not a fatal.
{code}
/**
* Light weight thread-safety check for multi-threaded access patterns
*/
private void checkOwner() {
Preconditions.checkArgument(ownerLock.isHeldByCurrentThread(),
"Owner thread expected %s, got %s",
ownerLock.getOwner(),
Thread.currentThread());
}
