I need to copy data from Hadoop cluster A to cluster B. I know I can use
distCp tool to do that. Now the problem is: cluster A has version 1.2.1 and
cluster B has version 0.20.x. So distcp tool from either version does not
work on both versions. Is there a possible way to do that? So far I
I am new to HBase. I am trying to check if a user is able to configure the

hbase/hadoop are all running on my local dev box as pseudo cluster. I
believe hbase/hadoop are all setup correctly since I can create hbase
tables, update hbase tables, run MR jobs etc.
The problem is:
Ted, do you have any public maven repository to download hbase client with
version hbase-0.95.1-hadoop1? I am kind of surprised that it becomes an issue.

Hi there,
I am writing Java program to access HBase and the version of Hbase I use is
0.95.1-hadoop1. The problem is: I failed to download the jar file for this
version from Maven central repository even though it is listed at the Maven
central repository
From HBase web site, I can only find the recent versions of HBase (e.g.
http://mirror.esocc.com/apache/hbase/). I like to download version 0.94.0, any
idea where can I find it? Thanks!
Thanks Ted. But it seems still not working after I add that repository: the
error message is the same.

There is a significant disparity between the reads from HDFS and from
HBase.

Hi there,
I know how to create MapReduce job with HBase data source only or HDFS file as
data source. Now I need to create a MapReduce job with mixed data sources, that
is, this MR job need to read data from both HBase and HDFS files. Is it
possible? If yes, could u share some sample code?
