Re: Dennis Mårtensson
Dennis, Hadoop is an open source project under the Apache Software Foundation. Anyone and everyone is welcome to contribute to it. There are no 'insiders' or 'outsiders' here when it comes to contributions :) You may start by picking up some low hanging fruits in MapReduce project, listed at our bug tracker: https://issues.apache.org/jira/secure/IssueNavigator!executeAdvanced.jspa?jqlQuery=project+%3D+MAPREDUCE+AND+resolution+%3D+Unresolved+AND+labels+%3D+newbie+AND+status+%3D+Open&runQuery=true&clear=true Feel free to reach out to us over common-dev@ or mapreduce-dev@ if you need some more help on any task! Some of us also hang out on #hadoop on FreeNode IRC, if you prefer that. On Tue, Jun 12, 2012 at 3:34 AM, Dennis Mårtensson wrote: > Hi my name is Dennis Mårtensson, > > I am a student and developer.
