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.
> use sequencefile as the default for storing intermediate results

> 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
