Hi All,
I have installed hadoop 0.20.1 on my system and set up a pseudo
cluster configuration.
Below is the core-site.xml I am using:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/tmp/hadoop-${user.name}</value>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:54310</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>hdfs://localhost:54311</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>mapred.child.java.opts</name>
<value>-Xmx512m</value>
</property>
</configuration>
Formatted hdfs using command "$ hadoop namenode -format" and I get no error.
Then I started-all components using "$ start-all.sh" and yet I get no error.
Env variables HADOOP_HOME etc are correctly defined.
Now I get the following errors:
$hadoop dfs -ls
ls: Cannot access .: No such file or directory.
$ hadoop dfs -copyFromLocal .vimrc .
$ hadoop dfs -ls
Found 1 items
-rw-r--r-- 3 nipunt supergroup 3051 2009-09-28 23:14 /user/nipunt
$ hadoop dfs -copyFromLocal .bashrc .
copyFromLocal: Target already exists
What is the root cause of the problem ?
How to overcome it ?
