HDFS - HBase replication not working

Question

I'm using Prediction-IO for a POC.

Issue : I have set HDFS replication factor as 1. If I create any sample file on HDFS , then replication factor is 1.

But whenever I try to load data using Prediction-IO( which uses HBase) then all files created have replication factor of 3.

Please help.

Answer 1

By default HBase will pick replication factor as 3. To specify replication factor add following property in hbase-site.xml

<property>
   <name>dfs.replication</name>
   <value>1</value>
</property>

I had to update hbase-site.xml on all region servers.
