[jira] Created: (HADOOP-1060) Lost tasktracker leads to hung jobs
Lost tasktracker leads to hung jobs
-----------------------------------
Key: HADOOP-1060
URL: https://issues.apache.org/jira/browse/HADOOP-1060
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.12.0
Reporter: Arun C Murthy
Priority: Critical
Fix For: 0.12.1
When the JobTracker detects that a TaskTracker is 'lost' and tries to fail the incomplete tasks and the completed map tasks it fails with:
2007-03-03 00:38:24,056 ERROR org.apache.hadoop.mapred.JobTracker: Tracker Expiry Thread got exception: java.lang.IndexOutOfBoundsException: Index: 310, Size: 307
at java.util.ArrayList.RangeCheck(ArrayList.java:546)
at java.util.ArrayList.get(ArrayList.java:321)
at org.apache.hadoop.mapred.JobInProgress.updateTaskStatus(JobInProgress.java:342)
at org.apache.hadoop.mapred.JobInProgress.failedTask(JobInProgress.java:862)
at org.apache.hadoop.mapred.JobTracker.lostTaskTracker(JobTracker.java:1637)
at org.apache.hadoop.mapred.JobTracker$ExpireTrackers.run(JobTracker.java:269)
at java.lang.Thread.run(Thread.java:595)
This means that the tasks aren't 'failed' correctly and the JT just assumes the task is running and never restarts the task... thereby leading to a hung job.

Arun C Murthy updated HADOOP-1060:
----------------------------------
Description:
When the JobTracker detects that a TaskTracker is 'lost' and tries to fail the incomplete tasks and the completed map tasks it fails with:

This means that the tasks aren't 'failed' correctly and the JT just assumes the task is running and never restarts the task... thereby leading to a hung job.

[jira] Updated: (HADOOP-1060) IndexOutOfBoundsException in
JobInProgress.updateTaskStatus leads to hung jobs
Posted by "Arun C Murthy (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-1060?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arun C Murthy updated HADOOP-1060:
----------------------------------
Attachment: HADOOP-1060_20070305_1.patch
Here is a patch which fixes the problem; basically the events-counter wasn't being manipulated correctly - also this fixes the JobClient to correctly handle lost trackers and fixes a synchronization issue in the JobTracker.
However there is an issue with this patch: With TASKTRACKER_EXPIRY_INTERVAL (set to the current default of 10mins) this patch works like a charm, I've tried manually bringing down trackers etc. and all unit-tests pass; however when I tried to test it with smaller expiry intervals (3m/5m) I see some weird behaviour; bringing this to everyone's attention while I dive deeper.
a) Set to 3mins i.e. ExpiryTrackerThread kicks in every minute
The JT goes into a tizzy and seems to get overloaded e.g. all IPCs from the JobClient timeout and eventually it kills the job.
b) Set to 3mins i.e. ExpiryTrackerThread kicks in every minute and a two-thirds
I see that the reduces hang with infinite logs of this nature:
