Subject Re: Phoenix Connector on Secure Cluster

Try using an hbase-site.xml (on both HBase server and presto-phoenix
client) with the following properties: hbase.security.authentication (set
to ‘kerberos’), hadoop.security.authentication (set to ‘kerberos’),
hbase.regionserver.kerberos.principal, hbase.regionserver.keytab.file,
hbase.master.kerberos.principal,hbase.master.keytab.file.  You also need to
make sure krb5.conf is in the right place for your OS, or else start the
Presto jvm with -Djava.security.krb5.conf=
