Sample Of Experienced Interview Questions
A few of the frequently asked Big Data interview questions for experienced professionals are:
1. What Will Be The Best Option When NameNode Is Down?
The process of NameNode recovery involves the following steps to make Hadoop cluster up and running:
a) Use the file system metadata replica to start a new NameNode.
b) Then, configure the DataNodes and customers so that they can acknowledge this new NameNode which has been started.
c) Now the new NameNode will start serving the customer after it has loaded the last checkpoint FsImage completely and received block reports from the DataNodes.
On large Hadoop clusters, this NameNode recovery procedure may take a lot of time and it becomes even a greater challenge in case of routine maintenance.
2. What is speculative execution in Hadoop?
If a node is executing a task slowly, the master node redundantly executes another instance of that same task on another node. Then, the task that finishes first will be accepted and the other one will be killed. This process is known as speculative execution in Hadoop.
