In advanced Hadoop cluster setups, how is high availability for the NameNode achieved?
- Active-Active Configuration
- Active-Passive Configuration
- Dynamic Replication
- Manual Failover
High availability for the NameNode is achieved in advanced setups through an Active-Passive configuration. In this setup, one NameNode is active, while the other remains passive, ready to take over in case of a failure. This ensures uninterrupted NameNode services and minimizes downtime.
