error building hadoop for hbase
Hi,
I am following the instructions here (
http://www.michael-noll.com/blog/2011/04/14/building-an-hadoop-0-20-x-version-for-hbase-0-90-2/#examples-use-git-not-svn)
to build my own hadoop distribution that can work with hbase-0.90.2 version.
I believe I need to do this to be able to run hbase in distributed mode.
But when i run 'ant mvn-install' on linux (amazon ec2 instance), i get this
error -
--------------
BUILD FAILED
/media/ephemeral0/git/hadoop-common/build.xml:1975: Problem: failed to
create task or type replaceregexp
Cause: the class org.apache.tools.ant.taskdefs.optional.ReplaceRegExp 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
-/home/ec2-user/.ant/lib
-a directory added on the command line with the -lib argument
Do not panic, this is a common problem.
The commonest cause is a missing JAR.
This is not a bug; it is a configuration problem
---------------------
when i run this on my windows machine, there is no .m2 directory.
Also, if someone can point me to an already built compatible hadoop
distribution for hbase-0.90.2, that would be great. That ways I won't have
to go through this trouble.
thanks
vinod
ps - i did google for 'Problem: failed to create task or type
replaceregexp'. But none of that really helped. I downloaded and copies
ant-nodeps-1.6.5.jar to /usr/share/ant/lib and that didn't work.

here are my answers -
*
*
*Why hbase 0.90.2 and not hbase 0.90.4, the latest release?*
I have a standalone setup of hbase (0.90.2) in my current production system
that has lots of data (~20GB). but its hosted on a m1.large and it is
running out of memory. our service is currently in alpha mode. we want to
get to beta soon. so my plan was to get a m1.xlarge ec2 instance and copy
over all the data from this host to new bigger host and run in distributed
mode. so to be safe, i am choosing hbase-0.90.2. is my approach correct?
*Make sure you have the ant optionals or an ant that includes all
dependencies as per the above message.*
yes i have ant optionals.
*That seems like an old verision of ant. Try a newer one?*
i am running ant 1.7.1. but when i did google search, i found a place to get
ant-nodejs.jar from 1.6.5 and i wanted to quickly try it out. ill get the
corresponding one and try it.
thanks

Why hbase 0.90.2 and not hbase 0.90.4, the latest release?

I'm not sure how .m2 gets set up on windows. Maybe you need to build
something w/ maven first (you could try building hbase).

http://hbase.apache.org/book.html#hadoop is our current hadoop story.
You could try one of the other offerings listed there -- e.g. CDH --
if you don't want to build hadoop yourself.
