Review request for hive.
Bugs: HIVE-11376
https://issues.apache.org/jira/browse/HIVE-11376
Repository: hive-git
Description
-------
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/io/CombineHiveInputFormat.java#L379
This is the exact code snippet:
{noformat}
/ Since there is no easy way of knowing whether MAPREDUCE-1597 is present in
the tree or not,
// we use a configuration variable for the same
if (this.mrwork != null && !this.mrwork.getHadoopSupportsSplittable()) {
// The following code should be removed, once
// https://issues.apache.org/jira/browse/MAPREDUCE-1597 is fixed.
// Hadoop does not handle non-splittable files correctly for
CombineFileInputFormat,
// so don't use CombineFileInputFormat for non-splittable files
//ie, dont't combine if inputformat is a TextInputFormat and has
compression turned on
{noformat}
