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.

The three modes in which Hadoop can be run are:

Standalone (local) mode - No Hadoop daemons running, everything runs on a single Java Virtual machine only.

Pseudo-distributed mode - Daemons run on the local machine, thereby simulating a cluster on a smaller scale.

Fully distributed mode - Runs on a cluster of machines.
