  - HPE Data Fabric Database Shell (JSON Tables)
    The mapr dbshell is a tool that enables you to create and perform basic manipulation of JSON tables and documents. You run dbshell by typing mapr dbshell on the command line after logging into a node in a HPE Data Fabric cluster.
  - Utilities for HPE Data Fabric Database JSON Tables
    HPE Data Fabric Database JSON provides utilities to copy, export, and import data, compare table content, and verify the consistency of secondary indexes.
  - HPE Data Fabric Database HBase Shell (Binary Tables)
    You can manage HPE Data Fabric Database tables using HBase shell commands and additional HBase shell commands included in the HPE Data Fabric distribution of Hadoop.

      The hadoop distcp command is a tool used for large inter- and intra-cluster copying.
    - hadoop fs
      The hadoop fs command runs a generic file system user client that interacts with the file system. Starting from EEP 7.1.0, all hadoop fs commands support operations on symlinks.
    - hadoop jar
      The hadoop jar command runs a program contained in a JAR file. Users can bundle their MapReduce code in a JAR file and execute it using this command.
    - hadoop job
      The hadoop job command enables you to manage MapReduce jobs.
    - hadoop mfs
      The hadoop mfs command displays directory information and contents, creates symbolic links and hard links, sets, gets, and removes Access Control Expressions (ACE) on files and directories, and sets compression and chunk size on a directory.
    - hadoop mradmin
      The hadoop mradmin command runs Map-Reduce administrative commands.
    - hadoop pipes
      The hadoop pipes command runs a pipes job.
    - hadoop queue
      The hadoop queue command displays job queue information.
    - hadoop version
      The hadoop version command prints the hadoop software version.
    - hadoop conf
      The hadoop conf command outputs the configuration information for this node to standard output.

Hadoop Syntax Summary

The following syntax summary applies to all commands.

hadoop [--config confdir] [COMMAND] [GENERIC_OPTIONS] [COMMAND_OPTIONS]

Hadoop has an option parsing framework that employs parsing generic options as well as running classes.

COMMAND_OPTION	Description
`-mode`	For both the hadoop and hadoop2 commands, setting this option is no longer valid. Both commands default to `yarn`, the only valid mode for the current Data Fabric version.
`--config confdir`	Overwrites the default Configuration directory. Default is `${HADOOP_HOME}/conf`.
`COMMAND`	Various commands with their options are described in the following sections.
`GENERIC_OPTIONS`	The common set of options supported by multiple commands.
`COMMAND_OPTIONS`	Various command options are described in the following sections.

NOTE

Running the hadoop script without any arguments prints the help description for all commands.
