Latest compatible version of hadoop and hbase

问题:

I have to install hadoop and hbase on 4 machines.
I have found latest version of hadoop-2.6.0 and hbase-0.98.9-hadoop2-bin.

1)Are they compatible?
2)How I should install hbase and hadoop on 4 machines i.e. how many masters and slaves etc.?

Answering your questions :

1. See the Hbase-Hadoop compatibility link . hbase-0.98.9 should support hadoop-2.6.0.

2. You have two options

   • 1 master node and 3 slave nodes. (Since you have only 4 nodes this configuration would be suffice)

   • If you wanted to enabled HA, you can go for 2 master nodes and 2 slave nodes.

Considering the first question, I was trying to find the answer myself and found this in hbase docs:

• "S" = supported

• "X" = not supported

• "NT" = Not tested
