Hadoop Jobs
You can run Hadoop jobs in 3 possible modes :
- Standalone (or local) mode: There are no daemons used in this mode. Hadoop uses the local file system as an substitute for HDFS file system. The jobs will run as if there is 1 mapper and 1 reducer.
- Pseudo-distributed mode: All the daemons run on a single machine and this setting mimics the behavior of a cluster. All the daemons run on your machine locally using the HDFS protocol. There can be multiple mappers and reducers.
- Fully-distributed mode: This is how Hadoop runs on a real cluster.
