hdfs-site.xml configuration

[rjudet]

You might want to set the hdfs in the following way in hdfs-site.xml, otherwise might get a java.net.URISyntaxException: Illegal character in opaque part at index 2:

   <property>
       <name>dfs.namenode.name.dir</name>
       <value>file:///C:/hadoop-2.8.0/data/namenode</value>
   </property>
   <property>
       <name>dfs.datanode.data.dir</name>
       <value>file:///C:/hadoop-2.8.0/data/datanode</value>
   </property>

Also, I think the JAVA_HOME and HADOOP_HOME environment variables should be set without the trailing /bin. Otherwise very good step by step instructions. Thanks.

I followed all steps as is it. They worked for me. I did not faced any errors. Please make sure you followed all steps, drive name, folder name as they have mentioned.

@rjudet are you able to resolve the issue?

[rjudet]

@MuhammadBilalYar yes, I was - as explained above. @carlvice To be more clear:

• JAVA_HOME env variable should NOT be set with a trailing /bin. In other words, if your installation is at C:\Program Files\Java\jdk1.8.0_xxx, THIS is what you set as JAVA_HOME, NOT C:\Program Files\Java\jdk1.8.0_25\bin. Same is available for HADOOP_HOME. Indeed, you will want to add to your PATH JAVA_HOME\bin, and similarly HADOOP_HOME\bin
• Yes, you can eventually get all components up and running. Did you try to use them though? I mean to even run an example word count Map Reduce program? That's when you might run into the java.net.URISyntaxException: Illegal character in opaque part at index 2. And if you do, you can get around it as I explained above.

Cheers

@carlvice - and I see that you in fact agree with me, and disperse my advice in the thread "Windows 10, Hadoop 2.7.6, JAVA_HOME error, classpath is not recognized". Maybe I should ask for royalties? lol

Sounds good!
