HBase does not run after ./start-hbase.sh - Permission Denied?

问题:

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 :)

回答1:

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...

回答2:

If you still have problem after changing the permission of start-hbase.sh then run following command

sudo chown -R hduser:hadoop /usr/local/hbase 

Give permission to 'hbase' directory to write log file..

I hope this will help to other folks...
