Vinod Kumar Vavilapalli resolved MAPREDUCE-5606. ------------------------------------------------ Resolution: Won't Fix I originally debugged the user.location bug with [~cnauroth]. It indeed is the same issue as MAPREDUCE-1144. We haven't done a 1.x release in ~2 years. Unlikely this issue is going to be fixed/released. This shouldn't happen in 2.x, which was a complete rewrite. Closing this as Won't Fix. > JobTracker blocked for DFSClient: Failed recovery attempt > --------------------------------------------------------- > > Key: MAPREDUCE-5606 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5606 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: jobtracker > Affects Versions: 1.0.3 > Environment: centos 5.8 jdk 1.7 > Reporter: firegun > Priority: Critical > > when a datanode was crash,the server can ping ok,but can not call rpc ,and > also can not ssh login. and then jobTracker may be request a block on this > datanode. > it will happened ,the JobTracker can not work,the webUI is also > unwork,hadoop job -list also unwork,the jobTracker logs no other info . > and then we need to restart the datanode. > then jobTraker can work too,but the taskTracker num come to zero, > we need run : hadoop mradmin -refreshNodes > then the JobTracker begin to add taskTraker ,but is very slowly. > this problem occur 5time in 2weeks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
