We should have at least two of each by default.\r\n\r\nAlso, we should write stderr from mappers/reducers to a file rather than a pipe; under the current implementation, mappers/reducers may end up blocked waiting for other mappers/reducers to finish before the master process reads their stderr.\r\n\r\n(I'm reluctant to throw another issue on the 0.3 release, but this should be really quick to do.)","comments":0,"title":"make local mode truly parallel by default","updated_at":"2011-10-07T23:00:39Z","url":"https://api.github.com/repos/Yelp/mrjob/issues/228","id":1850216,"assignee":{"avatar_url":"https://secure.gravatar.com/avatar/2b5b729537aaef280639ce21fc2194c1?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/davidmarin","id":50076,"login":"davidmarin"},"milestone":{"number":2,"created_at":"2011-04-11T21:25:40Z","due_on":null,"title":"v0.3.0","creator":{"avatar_url":"https://secure.gravatar.com/avatar/2b5b729537aaef280639ce21fc2194c1?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/davidmarin","id":50076,"login":"davidmarin"},"url":"https://api.github.com/repos/Yelp/mrjob/milestones/2","open_issues":4,"closed_issues":21,"description":"","state":"open"},"closed_at":null,"user":{"avatar_url":"https://secure.gravatar.com/avatar/2b5b729537aaef280639ce21fc2194c1?d=https://a248.e.akamai.net/assets.github.com%2Fimages%2Fgravatars%2Fgravatar-140.png","url":"https://api.github.com/users/davidmarin","id":50076,"login":"davidmarin"},"html_url":"https://github.com/Yelp/mrjob/issues/228","labels":[{"name":"Feature","url":"https://api.github.com/repos/Yelp/mrjob/labels/Feature","color":"008500"}],"state":"open"},"legacy":{"number":228,"action":"opened","issue":1850216}}
