Task Tracker Not Starting in Hadoop-1.0.3 Help Please
Dibyendu Karmakar 2012-12-04, 10:25
Hiii, I am new in hadoop. Trying to configure it in fully distributed mode.
But after the command bin/start-all.sh or bin/start-mapred.sh or
bin/hadoop-daemon.sh start tasktracker, TASKTRACKER IS GOING DOWN
IMMEDIATELY WITHOUT ANY ERROR IN LOG FILE.
HELP PLEASE...

I'm using hadoop 1.0.3 version.
I am using 2 computers -
172.16.4.12 (radix.itd.jusl.ac.in) - NAMENODE + JOBTRACKER + DATANODE
172.16.4.14 - DATANODE

My conf is somewhat -
< core-site.xml >
fs.default.name ------ hdfs://172.16.4.120:9001
hadoop.tmp.dir ------
/home/usr/student/pg/yr11/dibyendu_karmakar/hadoop-1.0.3/temp

< hdfs-site.xml >
dfs.replication -- 2
dfs.name.dir ---
/home/usr/student/pg/yr11/dibyendu_karmakar/hadoop-1.0.3/hadoop_name
dfs.data.dir --- /tmp/hadoop_data

< mapred-site.xml >
mapred.job.tracker --- 172.16.4.120:9002

< slaves >
172.16.4.14
172.16.4.120

< masters >
172.16.4.120

TASKTRACKER LOG FILE WITH NO ERROR -- ONLY INFO IS WRITTEN.
