Cannot create directory /home/hadoop/hadoopinfra/hdfs/namenode/current

Question

I get the error

Cannot create directory /home/hadoop/hadoopinfra/hdfs/namenode/current

While trying to install hadoop on my local Mac.

What could be the reason for this? Just for reference, I'm putting my xml files down below:

mapred-site.xml:

<configuration>

   <property> 
      <name>mapreduce.framework.name</name>
      <value>yarn</value>
   </property>
</configuration>

hdfs-site.xml:

<configuration>
    <property>
      <name>dfs.replication</name>
      <value>1</value>
    </property>

   <property>
      <name>dfs.name.dir</name>
      <value>file:///home/hadoop/hadoopinfra/hdfs/namenode </value>
   </property>

   <property>
      <name>dfs.data.dir</name> 
      <value>file:///home/hadoop/hadoopinfra/hdfs/datanode </value> 
   </property>
</configuration>

core-site.xml:

<configuration>
  <property>
    <name>hadoop.tmp.dir</name>
    <value>/usr/local/Cellar/hadoop/hdfs/tmp</value>
    <description>A base for other temporary directories.</description>
  </property>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value>
  </property>
</configuration>

I think my problem lies in my hdfs-site.xml file, but I'm not sure how to pinpoint/change it.

I'm using this tutorial, and "hadoop" in the file path is replaced by my username.

I had this problem too and it was a permission problem. I just did:

sudo chmod 777 /home/hadoop/hadoopinfra/hdfs/namenode/

and works!
