RE: Can't start pig

[Gabriel Laden]

Thanks to everybody for your help. Here are the answers to replies:

hadoopm is the hostname of the hadoop master.

Both of these telnet commands open a connection:
telnet hadoopm 9000
telnet hadoopm 9001

Also, here's some more more detail. In my hadoop conf/hadoop-site.xml, I have 
this, is it the problem for pig?
 <property>
    <name>fs.default.name</name>
    <value>hadoopm:9000</value>
  </property>

Then, I started up pig with DEBUG and got the following output, the last couple 
lines show the connection not working:

I guess the name of his jobtracker / namenode server. :)
Gabriel, make sure that you can connect to this server from the
computer you lunch your pig.
try
telnet hostname 9000
telnet hostname 9001
