---------------------------------------
Summary: Implement LocatedFileStatus & getFileBlockLocations to
provide node/localization information to Yarn/Mapreduce
Key: HDDS-2188
URL: https://issues.apache.org/jira/browse/HDDS-2188
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Filesystem
Affects Versions: 0.5.0
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
For applications like Hive/MapReduce to take advantage of the data locality in
Ozone, Ozone should return the location of the Ozone blocks. This is needed for
better read performance for Hadoop Applications.
{code}
if (file instanceof LocatedFileStatus) {
blkLocations = ((LocatedFileStatus) file).getBlockLocations();
} else {
blkLocations = fs.getFileBlockLocations(file, 0, length);
}
