What are the features of Standalone (local) mode?

By default, Hadoop run in a single-node, non-distributed mode, as a single Java process. Local mode uses the local file system for input and output operation. One can also use it for debugging purpose. It does not support the use of HDFS. Standalone mode is suitable only for running programs during development for testing. Further, in this mode, there is no custom configuration required for configuration files. Configuration files are:

  • core-site.xml
  • hdfs-site.xml files.
  • mapred-site.xml
  • yarn-default.xml

  • Google+
  • Pinterest
