Trying to connect to HBase database from Eclipse Scala program in Windows.
Cluster is secured using Kerberos Authentication, so its not connecting to the Hbase database.
Every time we are creating the jar file and running in the cluster. but this is not useful for development and debug.
How do i set the hbase-site.xml in classpath?
I downloaded *site.xml files tried adding the hbase-site.xml, core-site.xml and hdfs-site.xml as source folder and tried adding this files as external class folder from the project build path, but nothing is working. How do i make this working?
Is there anyway we can set the hbase-site.xml in sqlContext, since i am using sqlContext to read the Hbase tables using HortonWorks connector.
Error log is:
