use maven to compile ycsb - maven

Question

I want to run ycsb to test hbase, and I referred to this blog:
http://cloudfront.blogspot.in/2013/02/how-to-benchmark-hbase-using-ycsb.html#.Uy-J2XiLe1F
But when I changed pox.xml in /ycsb/hbase, I try to build ycsb using maven, then I got this error:
[ERROR] Failed to execute goal on project hbase-binding: Could not resolve dependencies for project com.yahoo.ycsb:hbase-binding:jar:0.1.4: Failure to find org.apache.hadoop:hadoop-core:jar:2.3.0 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
I've already successfully installed hadoop-2.3.0 and hbase-0.94.17.
Here is the pom.xml I use:
<?xml version="1.0" encoding="UTF-8"?>

Any help would be appreciated, thanks!

Answer 1

The problem is sometimes maven can't get the jars for hbase & hadoop. You will have to download them manually and add it to classpath.
