ls / worked. Thanks! I don't have a pig.jar, I only have pig-0.5.0-core.jar but
it seemed to have worked.
I didn't run ant. Do I need to? Ant fails when I run it.
BUILD FAILED
/usr/local/apps/pig-0.5.0/build.xml:237: Problem: failed to create task or type
jjtree
Cause: the class org.apache.tools.ant.taskdefs.optional.javacc.JJTree was not
found.
This looks like one of Ant's optional components.
Action: Check that the appropriate optional JAR exists in
-/usr/share/ant/lib
-/root/.ant/lib
-a directory added on the command line with the -lib argument

Hm, interesting. So it looks like you are now able to connect to HDFS
fine, but "ls" on an empty string dies. Try "ls /" (ls on an empty
string works for me, but I'm on trunk, which is halfway between 0.6
and 0.7).
If you continue to have trouble:
By pig.jar I mean the pig.jar that gets dropped into your pig
directory (such as /usr/local/apps/pig-0.5.0) when you run ant.
Do you know what's up with the "attempt to override final parameter"
messages? This is a Hadoop thing, not a Pig thing. Are you able to use
Hadoop? Seems like something may be misconfigured.
Can you send (or paste to pastebin) the logfile in
/usr/local/apps/pig-0.5.0/pig_1261587982689.log ?
BTW, undocumented (so far) tip: you can use pig.logfile in
pig.properties to specify an alternative directory for your logfiles,
if you don't like polluting the working directory with them.
As far as supporting HBase, you will want to apply the patch from
https://issues.apache.org/jira/browse/PIG-970 and rebuild.
