Date Mon, 01 Feb 2016 15:48:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15126424#comment-15126424

Chaoyu Tang commented on HIVE-1608:
-----------------------------------

More than one thousand tests failed, but most of them need only update their output files
to change the input format from org.apache.hadoop.mapred.TextInputFormat to and output format:
org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat and output format: org.apache.hadoop.hive.ql.io.HiveSequenceFileOutputFormat.

> The only argument for having a text file for storing intermediate results seems to be
better debuggability.
> But, tailing a sequence file is possible, and it should be more space efficient
