I've got a standalone HBase running on my local Windows 10 machine. It starts up fine, I can connect to it with hbase shell and do puts, gets, scans and deletes no problem. I'm very sure it is set up and working.
But connecting to it with Java has been a nightmare. It now seems to be looking for kerberos, but I haven't specified kerberos anywhere in my config and I am NOT trying to use kerberos:
Failed to complete request: org.apache.hadoop.hbase.MasterNotRunningException: org.apache.hadoop.hbase.MasterNotRunningException: java.io.IOException: Call to myHostName/myBindAddress:16000 failed on local exception: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]
Here's my setup in brief:
hbase-site.xml
<configuration>
<property>
<name>hbase.master.port</name>
<value>16000</value>
</property>
<property>
<name>hbase.master.info.bindAddress</name>
<value>localhost</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>false</value>
</property>
java code to connect from:
Configuration configuration = HBaseConfiguration.create();
// Have tried not adding the hbase-site.xml to config, seems to have no effect
configuration.addResource(new Path(hbaseSiteXMLPath));
// Manually specifying these just to be sure
configuration.set("zookeeper.znode.parent", "/hbase");
configuration.set("hbase.zookeeper.quorum", "localhost");
configuration.set("hbase.zookeeper.property.clientPort", "2181");
UserGroupInformation.setConfiguration(configuration);
Connection connection = ConnectionFactory.createConnection(configuration);
Table table = connection.getTable(TableName.valueOf(myTableName));
Result result = table.get(get);
table.close();
connection.close();
It may be relevant to add that I'm using Spring Framework and I'm still learning it so there's a chance that some autoconfiguration is possibly happening in my pom.xml? I'm posting it as well just in case its possible.

Any help appreciated.
