Jimmy Xiang created SPARK-5232:
----------------------------------
Summary: CombineFileInputFormatShim#getDirIndices is expensive
Key: SPARK-5232
URL: https://issues.apache.org/jira/browse/SPARK-5232
Project: Spark
Issue Type: Improvement
Reporter: Jimmy Xiang
[~lirui] found out that we spent quite some time on
CombineFileInputFormatShim#getDirIndices. Looked into it and it seems to me we
should be able to get rid of this method completely if we can enhance
CombineFileInputFormatShim a little.
