[ http://issues.apache.org/jira/browse/NUTCH-108?page=comments#action_12361339 ]
Paul Baclace commented on NUTCH-108: ------------------------------------ I just had the opportunity to test this with 33 tasktrackers. One thing I noticed: TaskTracker.java should be patched to reduce the redundant, voluminous output (unnecessary stack trace every 5 sec.) from the retry loop. All of the tasktrackers are now able to successfully reconnect. > tasktracker crashs when reconnecting to a new jobtracker. > --------------------------------------------------------- > > Key: NUTCH-108 > URL: http://issues.apache.org/jira/browse/NUTCH-108 > Project: Nutch > Type: Bug > Versions: 0.8-dev > Reporter: Stefan Groschupf > Priority: Critical > > 051008 213532 Lost connection to JobTracker [/192.168.200.100:7020]. > Retrying... > 051008 213537 Client connection to 192.168.200.100:7020: starting > 051008 213537 Client connection to 192.168.200.105:7030: closing > 051008 213537 Server connection on port 7030 from 192.168.200.105: exiting > 051008 213537 Server connection on port 7030 from 192.168.200.102: exiting > 051008 213537 Client connection to 192.168.200.102:7030: closing > 051008 213537 task_m_1iswra done; removing files. > 051008 213537 Server connection on port 7030 from 192.168.200.101: exiting > 051008 213537 Client connection to 192.168.200.101:7030: closing > Exception in thread "main" java.util.ConcurrentModificationException > at java.util.TreeMap$EntryIterator.nextEntry(TreeMap.java:1026) > at java.util.TreeMap$ValueIterator.next(TreeMap.java:1057) > at org.apache.nutch.mapred.TaskTracker.close(TaskTracker.java:134) > at org.apache.nutch.mapred.TaskTracker.run(TaskTracker.java:285) > at org.apache.nutch.mapred.TaskTracker.main(TaskTracker.java:629) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
