I want to run HBase. I have installed hadoop completely and when I run start-all.sh , it works fine and gives me this output:
hduser@CSLAP106:/usr/local/hadoop/bin$ jps 11956 SecondaryNameNode 12046 JobTracker 12193 TaskTracker 11800 DataNode 11656 NameNode 12254 Jps
But when I want to run start-hbase.sh , it gives me some errors of permission denied which I do not understand why:
hduser@CSLAP106:/usr/local/hbase/hbase-0.94.6.1/bin$ ./start-hbase.sh localhost: starting zookeeper, logging to /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-zookeeper-CSLAP106.out localhost: /usr/local/hbase/hbase-0.94.6.1/bin/hbase-daemon.sh: line 150: /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-zookeeper-CSLAP106.log: Permission denied localhost: head: cannot open ‘/usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-zookeeper-CSLAP106.out’ for reading: No such file or directory /usr/local/hbase/hbase-0.94.6.1/bin/hbase-daemon.sh: line 150: /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-master-CSLAP106.log: Permission denied head: cannot open ‘/usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-master-CSLAP106.out’ for reading: No such file or directory localhost: starting regionserver, logging to /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-regionserver-CSLAP106.out localhost: /usr/local/hbase/hbase-0.94.6.1/bin/hbase-daemon.sh: line 150: /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-regionserver-CSLAP106.log: Permission denied localhost: head: cannot open ‘/usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-hduser-regionserver-CSLAP106.out’ for reading: No such file or directory
after that, I tried to run sudo ./start-hbase.sh , and I got something more weird!
root@localhost's password:
I do not know what I am supposed to type here. anyway I just clicked Enter and it switched back to hduser again:
root@localhost's password: root@localhost's password: localhost: Permission denied, please try again. root@localhost's password: localhost: Permission denied, please try again. localhost: Permission denied (publickey,password). starting master, logging to /usr/local/hbase/hbase-0.94.6.1/bin/../logs/hbase-root- master-CSLAP106.out root@localhost's password: root@localhost's password: localhost: Permission denied, please try again. root@localhost's password: localhost: Permission denied, please try again. localhost: Permission denied (publickey,password). hduser@CSLAP106:/usr/local/hbase/hbase-0.94.6.1/bin$
I put some lines from my hbase-env.sh and hbase-site.xml files in case they are needed:
hbase-env.sh
# File naming hosts on which HRegionServers will run. $HBASE_HOME/conf/regionservers by default. export HBASE_REGIONSERVERS=/usr/local/hbase/hbase-0.94.6.1/conf/regionservers # File naming hosts on which backup HMaster will run. $HBASE_HOME/conf/backup-masters by default. export HBASE_BACKUP_MASTERS=/usr/local/hbase/hbase-0.94.6.1/conf/backup-masters # Tell HBase whether it should manage it's own instance of Zookeeper or not. export HBASE_MANAGES_ZK=true
hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:54310/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
So, what do you think is wrong with HBase that it does not run! I am really getting exhausted with this. It has been weeks I am working on it and every time it comes up with a new error. I would really appreciate your time and effort to help me 🙂

Answer
you say the output of ls -l start-hbase.sh is :
-rwxr-xr-x 1 root root 1872 huhti 4 2013 start-hbase.sh
if you want to know what user and group you are logging with , there us simple way:
touch test ls -l test
and check user:group …
the problem is user owner and group owner of script.. you have two solutions:
1) sudo chown hduser:hduser start-hbase.sh #here hduser is example...you should know what user and group you have,,,
inorder to make it your slave…with executable state(sudo chmod +x start-hbase.sh)
2) you can be root by: "su root" or "sudo su" or "sudo bash"
and then execute the script…
