In this way, you get to multiplex the work, which leads to better overall efficiency. There are a number of work schedulers available now (e.g. the fair share scheduler) which can be used to segregate jobs, and give them guaranteed resource allocations. See http://hadoop.apache.org/common/docs/r0.20.0/fair_scheduler.html for more details.<br /><br />Regarding your question about where to ask these questions - see the mailing lists at http://hadoop.apache.org/common/mailing_lists.html.<br /><br />Cheers,<br />TomTom Whitehttp://www.blogger.com/profile/02418758537880869494noreply@blogger.comtag:blogger.com,1999:blog-8898949683610477251.post-10266848902316301832009-08-05T18:17:03.602+01:002009-08-05T18:17:03.602+01:00Hi...<br />I bought your book, but I didnt find any info about how to do subclusters.<br /><br />in my research a want to specialize some regions of my hadoop cluster for example Sorting. other region for only joins, ... other region for only group by,...<br /><br />I dont know if you know what I mean.<br /><br />Where can i post problem?<br /><br />Thanks for allHarold Valdivia Garciahttp://www.blogger.com/profile/04923485024578705507noreply@blogger.comtag:blogger.com,1999:blog-8898949683610477251.post-80572494012991911192009-05-12T07:55:00.000+01:002009-05-12T07:55:00.000+01:00Congratulations Tom!Arun C Murthyhttp://people.apache.org/~acmurthynoreply@blogger.comtag:blogger.com,1999:blog-8898949683610477251.post-79506263338453771322009-05-09T19:32:00.000+01:002009-05-09T19:32:00.000+01:00Congrats Tom!Amrhttp://www.blogger.com/profile/11529287968790118650noreply@blogger.comtag:blogger.com,1999:blog-8898949683610477251.post-53988217400528403482009-05-07T22:54:00.000+01:002009-05-07T22:54:00.000+01:00Tom, was it really only a couple of months?
