Hi Shashi, Not sure i got your question right, but if its related to building of Hadoop on windows then i think what ever steps mentioned by James and Chris would be definitely help. But is your scenario to remotely(not on one of the nodes of cluster) access HDFS through java from either windows or linux machines ? In that case certain set of jars needs to be in client machine(refer hadoop-client/pom.xml) and subset of the server configurations (even if full not a problem) is required to access the HDFS and YARN
@Chris Nauroth, Are native components (winutils.exe and hadoop.dll), required in the remote machine ? AFAIK its not required, correct me if i am wrong ! + Naga ________________________________ From: Chris Nauroth [[email protected]] Sent: Monday, November 02, 2015 02:10 To: [email protected] Subject: Re: Utility to push data into HDFS In addition to the standard Hadoop jars available in an Apache Hadoop distro, Windows also requires the native components for Windows: winutils.exe and hadoop.dll.

I agree WebHDFS is one of the option to access hadoop from windows or *nix. I wanted to know if I can write a java code will can be executed from windows? Ex: java HDFSPut.java <<- this java code should have FSShell cammand (hadoop fs -ls) written in java. In order to execute this , what are list items I should have on windows? For example hadoop jars etc. If you can throw some light on this then it would be great help.

Another option would be WebHDFS, which just requires an HTTP client on your platform of choice. http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/WebHDFS.html --Chris Nauroth From: Shashi Vishwakarma <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Saturday, October 31, 2015 at 5:46 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Utility to push data into HDFS Hi I need build a common utility for unix/windows based system to push data into hadoop system.
