Subject How to start one nodemanager in HDP 2.0.6 ?
Date Tue, 20 May 2014 03:22:44 GMT
I'm using Hortonworks HDP 2.0.6. One of the nodes reboots and I want to
start nodemanager manually on that node, but the command
"/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh
start nodemanager" complains the following:

/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh: line 44:
/usr/lib/hadoop-yarn/sbin/../libexec/yarn-config.sh: No such file or
directory
mkdir: cannot create directory `/logs': Permission denied
chown: cannot access `/logs': No such file or directory
starting nodemanager, logging to
/logs/yarn-hadoop-nodemanager-a04.jsepc.com.out
/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh: line 124:
/logs/yarn-hadoop-nodemanager-a04.jsepc.com.out: No such file or directory
head: cannot open `/logs/yarn-hadoop-nodemanager-a04.jsepc.com.out' for
reading: No such file or directory
/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh: line 129:
/logs/yarn-hadoop-nodemanager-a04.jsepc.com.out: No such file or directory
/usr/lib/hadoop-yarn/sbin/yarn-daemon.sh: line 130:
/logs/yarn-hadoop-nodemanager-a04.jsepc.com.out: No such file or directory


I suppose that is caused by configuration-related issues (
/usr/lib/hadoop-yarn/sbin/../libexec/yarn-config.sh:
No such file or directory). So how should I start a nodemanager manually ?
