Xi Fang updated MAPREDUCE-5224:
-------------------------------
Description:
JobTracker today expects the system directory to be in the default file system
if (fs == null) {
fs = mrOwner.doAs(new PrivilegedExceptionAction<FileSystem>() {
public FileSystem run() throws IOException {
return FileSystem.get(conf);
}});
}
...
public String getSystemDir() {
Path sysDir = new Path(conf.get("mapred.system.dir",
"/tmp/hadoop/mapred/system"));
return fs.makeQualified(sysDir).toString();
}
In Cloud like Azure the default file system is set as ASV (Windows Azure Blob
Storage), but we would still like the system directory to be in DFS. We should
change JobTracker to allow that.
