[jira] [Commented] (FALCON-143) Enable Late data handling for hive tables

["Srikanth Sundarrajan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FALCON-143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13811017#comment-13811017 ] 

Srikanth Sundarrajan commented on FALCON-143:
---------------------------------------------

AbstractRerunHandler, LateRerunEvent, RetryHandler: since the number of parameters is down to 7, can the checkstyle be re-enabled ?

I see two properties being added to the coord: falconFeedStorageType, falconInputFeedStorageTypes in OozieFeedMapper. They seem to hold similar values. Are they redundant, if so can we avoid?

Looks good otherwise.

> HCat nor Hive APIs expose internal stats about a given partition. The only way to get the partition size is to get the location of the partition on HDFS and then use globStatus and contentSummary APIs. 
> With the addition of HIVE-5317, this is going to get more complicated with deltas and minor and major compactions with no locking.
> Need to work with hive to see if there will be an API or Falcon needs to understand the structure of the layout of the data on the file system.
