Hi Lars,
i am not using cygwin, i am using 3 ubuntu-10.04 machines.
Finally that problem i mentioned got resolved i.e now i can see the
following after i run bin/start-hbase.sh on my master machine,
hbase-master: starting zookeeper, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-zookeeper-vamshikrishna-desktop.out
starting master, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/logs/hbase-hduser-master-vamshikrishna-desktop.out
hbase-regionserver2: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-arun-desktop.out
hbase-regionserver1: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshi-laptop.out
hbase-master: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshikrishna-desktop.out
But still , if i do jps on both region server machines, HRegionServer
daemon is not seen.And i checked the logs on both the regionservere
machines, i.e
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshi-laptop.log
---(hbase-regionserver1)
and
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-arun-desktop.log
---(hbase-regionserver2)
i found the same in both .it is like this, (here vamshikrishna-desktop is
the master and namenode machine)
