Subject [jira] Commented: (HIVE-417) Implement Indexing in Hive
Date Sat, 25 Apr 2009 20:01:30 GMT

    [ https://issues.apache.org/jira/browse/HIVE-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12702769#action_12702769
] 

Prasad Chakka commented on HIVE-417:
------------------------------------

HIVE-1230 has changed the interface for RecordReader and it no longer has getPos() method.
The older interfaces are deprecated. I used this method in the prototype get the current position
while creating the index and also while reading the actual data file. Even the SequenceFileRecordReader
does not have this method. 

Without getPos() and seek() methods to RecordReader it becomes tough to implement any kind
of generic indexing.
