> Hive should merge empty files
> -----------------------------
>
> Key: HIVE-17257
> URL: https://issues.apache.org/jira/browse/HIVE-17257
> Project: Hive
> Issue Type: Bug
> Reporter: Chao Sun
> Assignee: Chao Sun
> Attachments: HIVE-17257.0.patch, HIVE-17257.1.patch,
> HIVE-17257.2.patch
>
>
> Currently if merging file option is turned on and the dest dir contains large
> number of empty files, Hive will not trigger merge task:
> {code}
> private long getMergeSize(FileSystem inpFs, Path dirPath, long avgSize) {
> AverageSize averageSize = getAverageSize(inpFs, dirPath);
> if (averageSize.getTotalSize() <= 0) {
> return -1;
> }
> if (averageSize.getNumFiles() <= 1) {
> return -1;
> }
> if (averageSize.getTotalSize()/averageSize.getNumFiles() < avgSize) {
> return averageSize.getTotalSize();
> }
> return -1;
> }
> {code}
> This logic doesn't seem right as the it seems better to combine these empty
> files into one.
