A number of commands in the File System Shell directly communicate with the HDFS and other file systems that it supports, including the S3 File System and the HFTP (Hadoop File System Implementation) File System.
Advanced Hadoop commands are typically used for more specialized or administrative tasks in a Hadoop cluster. Here are some advanced Hadoop commands and operations:
In the Hadoop ecosystem, basic Hadoop commands are frequently utilised for routine file and job operations, especially when working with the Hadoop Distributed File System (HDFS) and Hadoop MapReduce. These are a few fundamental Hadoop commands:
Here we are runing MapReduce jobs, we can specify additional parameters like hdfs input path , output path etc
Here we are monitoring detailed history information about a completed job.
Here we are monitoring detailed and modify Hadoop configuration parameters..
here we monitor report on the status of the HDFS cluster, including information about datanodes and blocks.
Refresh the list of datanodes in the Hadoop cluster.
Change the owner of files or directories in HDFS.
change and apply permission.
Safe mode is a maintenance state where HDFS is read-only and does not replicate or delete blocks.
