Siying Dong updated HIVE-1801: ------------------------------ Attachment: HIVE-1801.1.patch Still running tests. > HiveInputFormat or CombineHiveInputFormat always sync blocks of RCFile twice > ---------------------------------------------------------------------------- > > Key: HIVE-1801 > URL: https://issues.apache.org/jira/browse/HIVE-1801 > Project: Hive > Issue Type: Improvement > Reporter: Siying Dong > Assignee: Siying Dong > Attachments: HIVE-1801.1.patch > > > HiveInputFormat or CombineHiveInputFormat RCFile.Reader.sync() twice. 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.
