HBase does work on Hadoop with Security, but you will need the following in your hbase-site.xml
<property> <name>hbase.master.keytab.file</name> <value>/path/to/keytab/hbase.keytab</value> </property> <property> <name>hbase.master.kerberos.principal</name> <value>hbase/_h...@example.com</value> </property> <property> <name>hbase.regionserver.keytab.file</name> <value>/path/to/keytab/hbase.keytab</value> </property> <property> <name>hbase.regionserver.kerberos.principal</name> <value>hbase/_h...@example.com</value> </property> You need to set up a keytab for each box running hbase and you will need kerberos server and replace EXAMMPLE.COM<http://EXAMMPLE.COM> with the url Also with Yahoo!'s version, there is no append support so there is a risk of data loss. If this is just for testing/experimentation then that is fine, but if you want this to go into production you might want to look into Cloudera's latest release that has append + security.

Can I run it on this hadoop version? My guess is that it will work (where'd you find this branch?). Will Giraph not work on CDH? St.Ack
