Key: HIVE-1889
URL: https://issues.apache.org/jira/browse/HIVE-1889
Project: Hive
Issue Type: Improvement
Reporter: He Yongqiang
Assignee: He Yongqiang
In the current code, we use the whole hdfs path in index files to choose splits
to run mapreduce job.
If the data got moved or the name of the cluster got changed, the index data
should still be usable.
