Dear all,
I have first a problem with Hbase I am trying to install it on a distributed/multinode cluster..
I am using the cloudera https://ccp.cloudera.com/display/CDH4B2/HBase+Installation#HBaseInstallation-StartingtheHBaseMaster
But when I write this command
Creating the /hbase Directory in HDFS $sudo -u hdfs hadoop fs -mkdir /hbase
I get the following error:12/05/12 07:20:42 INFO security.UserGroupInformation: JAAS Configuration already set up for Hadoop, not re-installing.
And in all the next commands..
So any Help??
2. Another Aspect is when I start the hbase master it closes automatically after a while.
3. Also this command is not working$host -v -t A `namenode`namenode: command not found
Although when I run this command $hostname the output is namenode
So any help plz because I have deadlines and I want to test my application on hadoop's Hbase fully distributed mode...
Thanks,

This is not an error and you shouldn't be worried. It is rather a
noisy INFO log that should be fixed (as a DEBUG level instead) in
subsequent releases (Are you using CDH3 or CDH4? IIRC only CDH3u3
printed these, not in anything above that.)

Could you post us your HMaster start->crash log? You can use a service
like pastebin.com to send us the output.

> 3. Also this command is not working$host -v -t A `namenode`namenode: command not found

The right command is perhaps just:

$host -v -t A `hostname`

Dalia,

Is your NameNode running fine? The issue is that HBase Master has been
asked to talk to HDFS, but it can't connect to the HDFS NameNode. Does
"hadoop dfs -touchz foobar" pass or fail with similar retry issues?

What's your fs.default.name's value in Hadoop's core-site.xml? And
whats the output of that fixed host command I'd posted before?

Hi Shashwat,
I want to tell you about my configurations:
I am using 4 nodesOne "Master": Namenode, SecondaryNamenode, Job Tracker, Zookeeper, HMasterThree "Slaves": datanodes, tasktrackers, regionservers
In both master and slaves, all the hadoop daemons are working well, but as for the hbase master service it is not working..
As for region server here is the error:12/05/12 14:42:13 INFO util.ServerCommandLine: vmName=Java HotSpot(TM) 64-Bit Server VM, vmVendor=Sun Microsystems Inc., vmVersion=20.1-b0212/05/12 14:42:13 INFO util.ServerCommandLine: vmInputArguments=[-Xmx1000m, -ea, -XX:+UseConcMarkSweepGC, -XX:+CMSIncrementalMode, -Dhbase.log.dir=/usr/lib/hbase/bin/../logs, -Dhbase.log.file=hbase.log, -Dhbase.home.dir=/usr/lib/hbase/bin/.., -Dhbase.id.str=, -Dhbase.root.logger=INFO,console, -Djava.library.path=/usr/lib/hadoop-0.20/lib/native/Linux-amd64-64:/usr/lib/hbase/bin/../lib/native/Linux-amd64-64]12/05/12 14:42:13 INFO ipc.HBaseRpcMetrics: Initializing RPC Metrics with hostName=HRegionServer, port=6002012/05/12 14:42:14 FATAL zookeeper.ZKConfig: The server in zoo.cfg cannot be set to localhost in a fully-distributed setup because it won't be reachable.

The problem is your hbase is not able to connect to Hadoop, can you put your
hbase-site.xml content >> here.. have you specified localhost somewhere, if
so remove localhost from everywhere and put your hdfsl namenode address
suppose your namenode is running on master:9000 then put your hbase file
system setting as master:9000/hbase here I am sending you the configuration
which I am using in hbase and is working
My hbase-site.xml content is

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

Check this out, and also stop hbase, If its not stopping kill all the
processes, and after putting your  hdfs-site.xml, mapred-site.xml and
core-site.sml to hbase conf directory try to restart, and also delete the
folders created by hbase ,,, like temp directory or other then try to start.

I will try it but can u send me your core-site.xml and mapred-site.xml, hdfs-site.xml as well.
Have u added any lines to zoo.cfg ???

Hi,

There could be multiple issues, but it's strange to have in hbase-site.xml

  <value>hdfs://namenode:9000/hbase</value>

while the core-site.xml says:

<value>hdfs://namenode:54310/</value>

The two entries should match.

I would recommend to:
- use netstat to check the ports (netstat -l)
- do the check recommended by Harsh J previously.

Hiiii

I have tried to make both ports the same.
But the prob is the hbase cannot connect to port 8020.
When i run nmap hostname, port 8020 wasnt with the list of open ports.
I have tried what harsh told me abt.
I used the same port he used but same error occurred.
Another aspect in cloudera doc it says that i have to canonical name for the host ex: namenode.example.com as the hostname, but i didnt find it in any tutorial. No one makes it.
Note that i am deploying my cluster in fully distributed mode i.e am using 4 machines..

So any ideas??!!

In core-file.xml, do you have this?

<configuration>
<property>
<name>fs.default.name</name>
 <value>hdfs://namenode:8020/hbase</value>
</property>

If you want hbase to connect to 8020 you must have hdfs listening on
8020 as well.

Note that I have already disabled the firewall and I opened the port : ufw allow 8020
But when I run : telnet 10.0.2.3 8020 => connection refused ....
So the problem is that I cannot open the port..... :(
Note that I have tried it with other ports as 54310 and 9000 but same error occurs...

See the hosts file and hostname file looks fine... add this setting to all
your slaves and hosts.

Is it cumplsory to use CDH3u3 dist...? dont you download from apache. if
you want i can send you the preconfigured dist of apache...

did you do ssh to aal the machine and added the public key of master to all
slaves?? just remove localhost anywhere in conf files of hadoop and hbase...

Shashwat Shriparv

I did all what u said.

Yes I have to use it bec I already tried my code but on a standalone machine for cdh3u3.

But am mad from it its been now 20 days since I started deploying it and I only have one week to finish it bec I am sticked with deadlines.

Bas I think it wud be great if you send me your preconfigured dist of apache..

Here is the link from which you can download the preconfigured hadoop/hbase
,,,, just keep in mind please change the configuration according to your
machine and hostnames..

*http://dl.dropbox.com/u/19454506/Hadoop_HHH_Working.zip*
*
*
*
*
The video link i sent you its not just for the cluster on same pc if you
follow the steps you can configure a cluster on using physical pc.

and please let us know what code you are trying??

and what ever settings you have for the master node in hosts file just copy
the sam to the slaves also...

Last option if you are not able to do, let me take remote connection to
your pc i will do it.. but i dont think i will be needed :)

Hiiii shashwat,

Thanks for sharing your config files. But it seems that they are for pseudodistributed mode. I am using fully distributed mode on 4 PCs (one master and three slaves). Thus, it seems that these configs cannot work with mine...

Thanks,

Hi Dalia,
     Which version of hadoop and hbase are you using??Please add
hadoop-core-*.jar from your HADOOP_HOME and
commons-collections-3.2.1.jar from your HADOOP_HOME/lib directory into
your HBASE_HOME/lib directory and see if it works for you.

Regards,
    Mohammad Tariq
