------------------------------------
Summary: Search order for locations in HFileLink
Key: HBASE-27414
URL: https://issues.apache.org/jira/browse/HBASE-27414
Project: HBase
Issue Type: Improvement
Components: Performance
Reporter: Huaxiang Sun
Found that search order for locations is following the order of these locations
added to HFileLink object.
setLocations(originPath, tempPath, mobPath, archivePath);
archivePath is the last one to be searched. For most cases, hfile exists in
archivePath, so we can move archivePath to the first parameter to avoid
unnecessary NN query.
