[jira] Updated: (HADOOP-6218) Split TFile by Record Sequence Number

     [ https://issues.apache.org/jira/browse/HADOOP-6218?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raghu Angadi updated HADOOP-6218:
---------------------------------

    Attachment: HADOOP-6218-0.20.patch



Patch for 0.20 is attached.

It also includes previous 'createScanner' methods for backward compatibility. These methods are deprecated. 

I will add a unit test for both trunk and 0.20 patch later.

> It would be nice if TFile can be split by Record Sequence Number. This way, columnar storage like PIG-833 can align fields that belong to the same row but in different columns.
