One in getReader() and one in initIOContext(). We can avoid the latter one by read the sync() position of the former one. We also sync() twice for SequenceFile but since SequenceFileReader is not a part of Hive code, maybe we should be careful when depending on the implementation. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
