[jira] Created: (HADOOP-5140) setting fs.default.name to an invalid
URI format kills init thread in JobTracker
setting fs.default.name to an invalid URI format kills init thread in JobTracker
--------------------------------------------------------------------------------
Key: HADOOP-5140
URL: https://issues.apache.org/jira/browse/HADOOP-5140
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Affects Versions: 0.19.0
Reporter: sam rash
Priority: Minor
If you set fs.default.name in a JobConf object to something that causes java.net.URI to throw an IllegalArgumentException, the job not only fails initalization, but kills the JobInitThread

----------------------------------
and this manifests by the JobTracker never launching any more jobs (it receives ok and the jobs submitted count increases)

Steve Loughran commented on HADOOP-5140:
----------------------------------------
This is only loosely related to HADOOP-5687. That was bad failing on invalid fs.default.name values in the NN. This is bad handling of the (correct) failure to parse bad fs.default.name values. The changes I'm doing for HADOOP-5687 will change the error message to be more helpful, but you still need that code in the JobInitThread to catch the bad value during the cleanup process, which is what is apparently happening here.

code with the problem:
class JobInitThread implements Runnable {
public void run() {
JobInProgress job;
while (true) {
job = null;
try {
synchronized (jobInitQueue) {
while (jobInitQueue.isEmpty()) {
jobInitQueue.wait();
}
job = jobInitQueue.remove(0);
}
job.initTasks();
} catch (InterruptedException t) {
break;
} catch (Throwable t) {
LOG.error("Job initialization failed:\n" +
StringUtils.stringifyException(t));
if (job != null) {
job.fail();
}
}
}
}
}
job.fail() eventually calls garbageCollect() which trys to get the filesystem from the jobconf. The same exceptoin as above will occur when it trys to cleanup the dfs tmp dir, but this time it's not caught (being thrown inside the catch() block) and kills the JobInitThread
