Fix Javadoc for DistributedCache usage
--------------------------------------
Key: HDFS-1098
URL: https://issues.apache.org/jira/browse/HDFS-1098
Project: Hadoop HDFS
Issue Type: Bug
Components: documentation
Affects Versions: 0.20.2
Reporter: Ted Yu
Fix For: 0.20.3
The Javadoc for using DistributedCache isn't up-to-date with code:
* JobConf job = new JobConf();
* DistributedCache.addCacheFile(new URI("/myapp/lookup.dat#lookup.dat"),
* job);
This is the new API:
public static void addCacheFile(URI uri, Configuration conf) {
Javadoc should (partially) reflect the actual usage from TaskRunner:
p[i] = DistributedCache.getLocalCache(files[i], conf,
new Path(baseDir),
fileStatus,
false, Long.parseLong(
fileTimestamps[i]),
new Path(workDir.
getAbsolutePath()),
false);
}
DistributedCache.setLocalFiles(conf, stringifyPathArray(p));
