I eventually determined that bin/ycsb (a python script) was causing most
of the linkage problems, so I recommend using your own bash script to
start ycsb for HBase. The problem is that the ordering of paths in the
classpath is completely uncontrolled: bin/ycsb does not put the
hbase-binding/conf first, so it can pick up a default hbase-site.xml
found in a jar, and it will recursively include any jars in any
subdirectories under hbase-binding/ (a surprise when I mv'ed some files
to a subdir like dont_use_these and lsof showed them to be in use).
I ended up using hbase 0.95.1 hadoop1 on Apache Hadoop 1.0.4 for my
benchmarking.

0.95.2 is not yet finished. As Ted suggested, you can build HBase locally
from the sources (the 0.95 branch is usually good as the patches are tested
before being committed).
When 0.95.2 will be out I will redo the integration with ycsb. Hopefully it
will be simple to make it work with all hadoop versions on the standards
maven repo...

You can perform the following command in 0.95 workspace:
mvn clean install -DskipTests

I've just rechecked with the last 0.97 as of now, it does compile. It
worked as well 2 weeks ago with the 0.95 branch. I'm not sure about the
95.1. I remember some nasty maven issues.
((I rather be attacked by angry ants than nasty mavens.))
If you're using the maven repo for the 0.95.1, IIRC there is no version
available that works well with hadoop 2 with a maven-built client (it's
ok
if you build hbase locally with the right hadoop version).
Is there an experimental or nightly 0.95.2 maven repo I can connect to? I
can probably use 0.95.2 if all the tests passed; it looks like
https://builds.apache.org/job/**HBase-0.95/373<
https://builds.apache.org/job/HBase-0.95/373>passed.

Thanks for your help, Nicolas. I adjusted the params and I get a
ycsb/db/HBaseClient.java compile error (below) without any missing
package
errors, so I'm wondering how it can work for you. I am building by
adding
artifacts from 0.95.1 release to my .m2; and you are building a
snapshot
and "installing" that to .m2 (or other repo), I assume.
It appears to be missing hbase-common which I added to .m2 and the
compiler debug shows a classpath that only contains
hbase-server-0.95.1-hadoop2.****jar (plus ycsb and general jars). Does
your
mvn -X compile cmd line for ycsb/db/HBaseClient.java contain more hbase
or
hadoop jars? Do you have a settings.xml that makes mvn pull in more
dependencies?

Built it with:

SNAPSHOT
-Dhadoop.profile=2.0 -Dhadoop-two.version=2.0.5
(obviously, change the hbase.version & hadoop-two.version as you
need).
I'm awaiting the finalized hadoop2 flags in hbase pom to update this
and
push it to the main ycsb repo.
Cheers,

Hi Paul,
I think Nicolas Liochon maintains a personal set of branches for
this.
Maybe he can point you in the right direction.
Thanks,

I have been unable to build ycsb for hbase 0.95.1 hadoop2, even
though
I
added the artifacts to my local repo like so:
mvn install:install-file -Dfile=../hbase-0.95.1-**

-DgroupId=org.apache.hbase
-DartifactId=hbase-client -Dversion=0.95.1-hadoop2 -Dpackaging=jar
I looked at the pom.xml in the jar files to determine the
parameters,
modified ycsb pom.xml and hbase/pom.xml; ycsb "mvn clean package"
has
errors, not finding basic stuff:

is not ready for packaging changes made in hbase 0.95 OR could it be
that
adding jars to a local maven repo, because they are not yet on a
centralized server, simply does not suffice because not all
dependencies
are added? HBaseConfiguration is in
hbase-common-0.95.1-hadoop2.***
***jar
,
but how to add all the turtles all the way down?
What's the secret to using ycsb for the latest HBase?
