Hi,
There are two ways one can add secondary indexing to HBase.
One is from $HBASE_HOME/contrib/transactional/ *.jar and the other is from
$HBASE_HOME/contrib/indexed/*.jar
In setting up transactional, you need to following in hbase-site.xml:
<!-- Indexing Setup -->
<property>
<name>hbase.regionserver.class</name>
<value>org.apache.hadoop.hbase.ipc.IndexedRegionInterface</value>
<description> Required for secondary indexing. </description>
</property>
<property>
<name>hbase.regionserver.impl</name>
<value>org.apache.hadoop.hbase.regionserver.tableindexed.IndexedRegionServer</value>
<description> Required for secondary indexing. </description>
</property>
and for Indexing we set the following:
<property>
<name>hbase.hregion.impl</name>
<value>org.apache.hadoop.hbase.regionserver.IdxRegion</value>
</property>
So it looks like that they can co-exist.Is this not the case?
Thx
-Mike
