Hi, Please that is my real problem. Could you please look into my code in attached and tell me how I can update this, please ?
How to set a job jar file?
And now, here is my hdfs-site.xml
==
-bash-4.1$ cat conf/hdfs-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>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>/tmp/hadoop-hadoop/dfs/data</value>
</property>
</configuration>
-bash-4.1$

Could you advice on how to solve the error of “input path does not exist”?
Standing by …
Cheers

Hi have you set a class in your code ?
WARN mapred.JobClient: No job jar file set. User classes may not be found. See
JobConf(Class) or JobConf#setJar(String).
Also you need to check the path for your input file
Input path does not exist: hdfs://latdevweb02:9000/home/hadoop/hadoop/input
These are pretty straight forward errors resolve them and you should be good to
go.

is this is a valid path on hdfs? Can you access this path outside of the
program? For example using hadoop fs -ls command? Also, was this path and files
in it, created by a different user?
The exception seem to say that it does not exist or the running user does not
have permission to read it.
