Question - What are the three modes in which Hadoop can run?
Answer -
The three modes in which Hadoop can run are :
- Standalone mode: This is the default mode. It uses the local FileSystem and a single Java process to run the Hadoop services.
- Pseudo-distributed mode: This uses a single-node Hadoop deployment to execute all Hadoop services.
- Fully-distributed mode: This uses separate nodes to run Hadoop master and slave services.
