amazon web services - Allow more than one hadoop/EMR tasks to fail before shutting down -


i'm trying use hadoop on amazon elastic mapreduce have thousands of map tasks perform. i'm ok if small percentage of tasks fail, however, amazon shuts down job , lose of results when first mapper fails. there setting can use increase number of failed jobs allowed? thanks.

here's answer hadoop:

is there property define failed mapper threshold

to use setting described above in emr, at:

http://docs.aws.amazon.com/elasticmapreduce/latest/developerguide/emr-plan-bootstrap.html#predefinedbootstrapactions_configurehadoop

specifically, create xml file (config.xml in example) setting want change , apply bootstrap action:

./elastic-mapreduce --create \ --bootstrap-action s3://elasticmapreduce/bootstrap-actions/configure-hadoop \ --args "-m,s3://myawsbucket/config.xml"

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
