Hello everyone,
Can you please help me out to the below scenarios.
1) While using Hadoop V2, do we use Secondary NameNode in production environment?
2) For Hadoop V2, suppose we use muliple NameNodes in active/passive connection for High Availability and when the Edits Log file is growing huge,
How does the edits log gets applied to fsimage? If so, then applying the huge Edits log to Namenode would be time consuming? (We had Secondary NameNode in hadoop v1 to solve this problem)
Please help and many thanks
