i understand in hadoop, large input file splits small files , gets processed in different nodes map functions. got know can customize inputsplit s. know if following type of customization possible inputsplit : i have large input file coming in hadoop, want subset of file, i.e. set of lines in file go along every input split. mean data chunks of large file should contain these set of lines, irrespective of whatever way file split. to make question more clear, if need compare part of input file (say a ) rest of file content, in case inputsplit s going map function need have a part comparison. kindly guide me on this. theoretically possible split big file (a, b, c, d, ...) splits (a, b), (a, c), (a, d), ... . you'd have write lot of custom classes purpose. filesplit , extends inputsplit , says split file begins @ position start , has fixed length . actual access file done recordreader , i.e. linerecordreader . have implement code, read not actual split, header (p

the issue i'm trying solve follows: i have process ingests data file , inserts things in multiple tables, done 1 transaction, large data sets rollback or commit time out , fail, no matter set time out (at least far attempts have shown me). decided need rewrite functionality "chop" task up. stands pseudo code current code looks (pseudo code used avoid unnecessary information) variable = functionthatreadsfromafile(); itransactionmanager transactionobject = new transactionmanager(); idbtransaction dbtransaction = transactionobject.get(); writetofirsttable(variable ,dbtransaction); writetosecondtable(variable ,dbtransaction); writetothirdtable(variable ,dbtransaction); if(!error) transactionobject.commit(dbtransaction); else transactionobject.rollback(dbtransaction); like said, works fine smaller data sets, when file has more particular amount of rows (dependent on time out) fails on commit or rollback. i can't change time out 10,000 seconds example, in fac

i use recovery strategy. somehow ended in position 1 commit dropped 3 days worth of commits. and got pushed . committer isn't sure whether did forced push or what, we're in position. , 10 additional commits have been pushed since "bad" one. all of old commits there , piece together, i'm hoping git can me out. suppose cherry-pick range of commits between point , point b, there better? most, not all, of changes local 1 directory , i'd rather not manually inspect each one. what's right approach here remembering has been pushed upstream? git reset --hard <one commit before bad commit> git cherry-pick <the range of commits you've lost> git pull this way simulate on last commit (with reset ). create new commits locally ( cherry-pick ). pull in changes (and maybe merge conflicts).

i've created registration page whch checks errors , prints them out user. example if not have valid email address says invalid email address. @ top logic done lets webpage know if there errors later can register them without errors. in bottom html trying printout errors show next text field. have created errors reason print before user prints anything. code follows: <form action="" method="post"> <input type="hidden" name="action" value="register" /> <?php if(@$_post['action'] == 'register') { } <input type="text" name="firstname" maxlength = "16" class="text-bars" placeholder="firstname"/> <input type="text" name="lastname" maxlength = "16" class="text-bars" placeholder="lastname"/><b

i'm practicing ruby meta-programming , trying write own loop method handle of ugliness in listening socket, give programmer chance specify loop break condition , block of things after each io.select/sleep cycle. what want able write this: x = 1 while_listening_until( x == 0 ) x = rand(10) puts x end what i've been able make work is: def while_listening_until( params, &block ) break_cond = params[ :condition ] || "false" loop { #other listening things happening here yield break if params[:binding].eval( break_cond ) } end x = 1 while_listening_until( :condition => "x==0", :binding => binding() ) x = rand(10) puts x end so, how make eval , binding ugliness go away? this lambdas handy: def while_listening_until( condition, &block ) loop { #other listening things happening here yield break if condition.call } end x = 1 while_listening(lambda{ x == 0 }) x = rand(10) puts x en

i think must missing obvious, can't use preventdefault cancel navigating link's href when link tapped on ipad (it works ok on android phone though). i have simple test page, has on: <a id="mn" href="http://www.google.com">some link</a> <script> document.write('<script src=js/' + ('__proto__' in {} ? 'zepto.min' : 'jquery-1.6.2.min') + '.js><\/script>'); if ('__proto__' in {}) { document.write('<script src=js/touch.js><\/script>'); } $(document).ready( function() { $('#mn').tap(function(e) { e.preventdefault(); e.stoppropagation(); }); } ); </script> the tap event called, if stick alert in there fires ok, action of clicking link never cancelled. missing?! thanks, toby
