HBase can't creates its directory in HDFS

I'm following this tutorial to install hbase and hadoop but I'm facing a problem.

Everything is fine until the last step

HBase creates its directory in HDFS. To see the created directory, browse to Hadoop bin and type the following command.

$ ./bin/hadoop fs -ls /hbase If everything goes well, it will give you the following output.

Found 7 items drwxr-xr-x - hbase users 0 2014-06-25 18:58 /hbase/.tmp

...

but when I run this command I get /hbase :No such file or directory

This is my config

Hadoop configuration

core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

hdfs-site.xml

<configuration>
   <property>

   <property>

    </property>
</configuration>

Hbase configuration hbase-site.xml

<configuration>
   <property>
   <name>hbase.rootdir</name>
   <value>hdfs://localhost:8030/hbase</value>
</property>
   <property>
      <name>hbase.zookeeper.property.dataDir</name>
      <value>/home/marc/zookeeper</value>
   </property>
   <property>
       <name>hbase.cluster.distributed</name>
       <value>true</value>
    </property>
</configuration>

I can browse http://localhost:50070 and http://localhost:8088/cluster

How can I troubleshoot this?

EDIT

Based on Saurabh Suman's answer, I created the hbase folder but it stays empty.

In hbase-marc-master-marc-pc.log, I have the following exception. Is it related?

Your HDFS seems to be running on port 9000 while your HBase site is trying to connect to port 8030. - Felipe Martins Melo

The log indicates that HBase has issues with becoming an active master and therefore it starts to shutdown.

My assumption is that HBase was never able to start properly and therefore it didn't create the /hbase directory on its own. Further, this would be the reason why the /hbase directory is still empty.

I reproduced your error on my virtual machine and fixed it with this modified setup.

OS CentOS Linux release 7.2.1511

Virtualization software Vagrant and Virtualbox

Java

java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-b12)

Directory owner and permission adjustments

sudo su # Become root user
cd /usr/local/

chown -R hadoop:root hadoop
chmod -R 755 hadoop

chown -R hadoop:root Hbase
chmod -R 755 Hbase

Result

After starting HBase with this setup, it automatically created the /hbase directory and filled it with contents.

[hadoop@localhost conf]$ hdfs dfs -ls /hbase

We need to edit only those thing in configuration files which can't be created by itself. so,you need to manually create the directory in HDFS. hdfs dfs -mkdir /hbase
