hadoop fs commands are showing the local filesystem not the hdfs

Question

I installed hadoop in several laptops in order to form a hadoop cluster. First we installed in pseudo-distributed mode, and in all except one verything was perfect (i.e. all the services run, and when I do tests with hadoop fs it shows the hdfs). In the aftermentioned laptop (the one with problems) the `hadoop fs -lscommand shows the information of the local directory not the hdfs, the same happens with the commands -cat, -mkdir, -put. What could I be doing wrong?

Any help would be appreciated

Here is my core-site.xml

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

<!-- Put site-specific property overrides in this file. -->

<configuration>
<property>
 <name>hadoop.tmp.dir</name>
 <value>/home/hduser/hdfs_dir/tmp</value>
 <description></description>
</property>

<property>
 <name>fs.default.name</name>
 <value>hdfs://localhost:54310</value>
 <description>.</description>
</property>
</configuration>

I must said, that this is the same file for all the other laptops, and they work fine.

Answer 1

I had the same problem, and I had to make sure fs.default.name's value included a trailing / to refer to the path component:

<property>
 <name>fs.default.name</name>
 <value>hdfs://localhost:54310/</value>
 <description>.</description>
</property>

Answer 2

check that fs.default.name in core-site.xml points to the correct datanode in ex:

<property>
     <name>fs.default.name</name>
     <value>hdfs://target-namenode:54310</value>
</property>
