Hi,
I deploy hadoop cluster use two machine.one as a namenode,and the other
be used a datanode.
My namenode machine hostname is namenode1,and datanode machine hostname
is datanode1.
when I use command ./start-all.sh on namenode1,the console display below
string,
root@namenode1:/opt/hadoop/bin# ./start-all.sh
starting namenode, logging to
/opt/hadoop/bin/../logs/hadoop-root-namenode-namenode1.out
datanode1: starting datanode, logging to
/opt/hadoop/bin/../logs/hadoop-root-datanode-datanode1.out
namenode1: starting secondarynamenode, logging to
/opt/hadoop/bin/../logs/hadoop-root-secondarynamenode-namenode1.out
starting jobtracker, logging to
/opt/hadoop/bin/../logs/hadoop-root-jobtracker-namenode1.out
datanode1: starting tasktracker, logging to
/opt/hadoop/bin/../logs/hadoop-root-tasktracker-datanode1.out
and use jps show java processs,display below string,
15438 JobTracker
15159 NameNode
15582 Jps
15362 SecondaryNameNode
and ssh datanode1,use comman jps,display below somethins strings
21417 TaskTracker
21497 Jps
so,the datanode can't run,and I find logs
[root@datanode1 logs]# ls
hadoop-root-datanode-datanode1.out hadoop-root-tasktracker-datanode1.log
hadoop-root-tasktracker-datanode1.out.2
hadoop-root-datanode-datanode1.out.1 hadoop-root-tasktracker-datanode1.out
hadoop-root-datanode-datanode1.out.2 hadoop-root-tasktracker-datanode1.out.1
[root@datanode1 logs]# cat hadoop-root-datanode-datanode1.out
Unrecognized option: -jvm
Could not create the Java virtual machine.
Next, what should I do to solve this problem。
Thanks. devilsp
