Mikhail Bautin updated HIVE-3809: --------------------------------- Attachment: 0001-HIVE-3809-Decompressors-should-only-be-returned-to-t.patch Attaching a manually generated patch. > Concurrency issue in RCFile: multiple threads can use the same decompressor > --------------------------------------------------------------------------- > > Key: HIVE-3809 > URL: https://issues.apache.org/jira/browse/HIVE-3809 > Project: Hive > Issue Type: Bug > Reporter: Mikhail Bautin > Priority: Critical > Attachments: > 0001-HIVE-3809-Decompressors-should-only-be-returned-to-t.patch, D7419.1.patch > > > RCFile is not thread-safe, even if each reader is only used by one thread as > intended, because it is possible to return decompressors to the pool multiple > times by calling close on the reader multiple times. Then, different threads > can pick up the same decompressor twice from the pool, resulting in > decompression failures. -- This message is automatically generated by JIRA.
