RussianChange the value of hbase.rootdir from hdfs://localhost:9000/hbase to hdfs://localhost:8020/hbase in hbase-site.xml, and restart HBase.
HMASTER fails to run in psedo distributed mode
Question
I have installed hadoop 1.2.0 on Ubuntu.. All the services namenode, sec namenode, datanode, jobtracker, tasktracker running well.
I then installed hbase-0-94.8 and I hope, configurations are okay as well. But HMaster fails to start on port 9000.. It actually starts and then drops down.
I have self ssh on. It is working
my /etc/hosts entires,
127.0.0.1 localhost prakashl
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

I copied jar files from hadoop folders to hbase/lib folder to address incompatibilities if any.
