I have setup a Hadoop cluster containing 5 nodes on Amazon EC2. Now, when i login into the Master node and submit the following command bin/hadoop jar <program>.jar <arg1> <arg2> <path/to/input/file/on/S3> It throws the following errors (not at the same time.) The first error is thrown when i don't replace the slashes with '%2F' and the second is thrown when i replace them with '%2F': 1) Java.lang.IllegalArgumentException: Invalid hostname in URI S3://<ID>:<SECRETKEY>@<BUCKET>/<path-to-inputfile> 2) org.apache.hadoop.fs.S3.S3Exception: org.jets3t.service.S3ServiceException: S3 PUT failed for '

We have 3 public facing web applications which we are migrating to Azure. All sites use port 80. OPTIONS As far as I understand, there are three different options when using Web Roles: 1. All 3 sites hosted in ONE web role in a single cloud service : HTTP access can be configured by hostHeader in ServiceDefinition.csdef This is the cheapest Requires that all projects need to be published at the same time The sites cannot be scaled separately, only as a whole 1 Cloud Service project in Visual Studio 2. Each site hosted on a SEPARATE web role in a single cloud service : HTTP access can be

Here is a sample of GAE Console log record: http://i.stack.imgur.com/M2iJX.png for readable high res version. I would like to provide a breakdown of the fileds, displayed both in the collpased (summary) view and the expended (detail) view. I will fill the fields I know their meaning and would appreciate assistannce with dichipering the rest. This post will be updated once new information is available. Thank you, Maxim. Open issues: How to read timestamp? [...-prod/0-0-39. 346862139187007139 ] Why in summary it says request took 343ms but in details is says 344ms ? If request spend 123ms on cpu

Is is possible to run a Node.js TCP Socket oriented application on the Cloud , more specifically on Heroku or AppFog . It's not going to be a web application, but a server for access with a client program. The basic idea is to use the capabilities of the Cloud - scaling and an easy to use platform. I know that such application could easily run on IaaS like Amazon AWS , but I would really like to take advantage of the PaaS features of Heroku or AppFog . I am reasonably sure that doesn't answer the question at hand: "Is is possible to run a Node.js TCP Socket oriented application". All PaaS

Is there any way to update files stored on Amazon CloudFront (Amazon's CDN service)? Seems like it won't take any update of a file we make (e.g. removing the file and storing the new one with the same file name as before). Do I have to explicitly trigger an update process to remove the files from the edge servers to get the new file contents published? Thanks for your help Amazon added an Invalidation Feature. This is API Reference . Sample Request from the API Reference: POST /2010-08-01/distribution/[distribution ID]/invalidation HTTP/1.0 Host: cloudfront.amazonaws.com Authorization: [AWS

Preface I've been shopping around for cloud based hosting solutions, particularly MS Azure & Amazon's EC2. They, Microsoft and Amazon , have pricing tables which describe a "cost/hour"/"compute hour." Question When they say "cost/hour" or "compute hour," what's in an hour? Is it the amount of time an application pool, in the case of an ASP.NET app, is active? Or, the amount of time that your application is active? Or, is it related in some manner to the incoming requests per hour/minute? Is there a possibility that if the app is not active (serving requests) it's not factored into the overall
