Thanks Benjamin. 1. I was wondering how can I run mesos-master and slaves as daemon process. Nohup is giving me issues to launch them from remotely.
3. I have build mesos from trunk and starting meso master and slave by --- Mesos-master *nohup /usr/local/mesos-spark/mesos/bin/mesos-master.sh --log_dir=/usr/local/mesos-spark/mesos/work >> /tmp/mesos-master.txt &* * * *ln -s lt-mesos-master.INFO mesos-master.INFO* *ln -s lt-mesos-master.ERROR mesos-master.ERROR* *ln -s lt-mesos-master.WARNING mesos-master.WARNING* Mesos-slave --- (Note I need to create links to all log files to enable logging from mesos web url) *nohup /usr/local/mesos-spark/mesos/bin/mesos-slave.sh --master=br9:5050 --log_dir=/usr/local/mesos-spark/mesos/work >> /tmp/mesos-slave.txt &* *cd /usr/local/mesos-spark/mesos/* *chmod 777 -R work* *cd work* *ln -s lt-mesos-slave.ERROR mesos-slave.ERROR* *ln -s lt-mesos-slave.WARNING mesos-slave.WARNING* *ln -s lt-mesos-slave.INFO mesos-slave.INFO* I see only these suspicious lines in lt-mesos-master.ERROR Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg E0918 04:28:37.111768 28729 files.cpp:92] Error attaching path '/usr/local/mesos-spark/mesos/work/mesos-master.INFO': Failed to canonicalize /usr/local/mesos-spark/mesos/work/mesos-master.INFO into an absolute path E0918 04:28:37.112239 28731 master.cpp:535] Failed to attach log file: Failed to canonicalize /usr/local/mesos-spark/mesos/work/mesos-master.INFO into an absolute path Regards, Praveenesh On Wed, Sep 19, 2012 at 12:26 PM, Benjamin Mahler <[email protected]>wrote: > 1.
