------------------------------------
Summary: The error handler in LlapRecordReader might block if its
queue is full
Key: HIVE-22523
URL: https://issues.apache.org/jira/browse/HIVE-22523
Project: Hive
Issue Type: Bug
Reporter: Attila Magyar
Assignee: Attila Magyar
Fix For: 4.0.0
In setError() we set the value of an atomic reference (pendingError) and we
also put the error in a queue. The latter seems not just unnecessary but it
might block the caller of the handler if the queue is full. Also closing of the
reader is might not properly handled as some of the flags are not volatile.
