Oozie: run at some time or at some frequency, whichever comes first -

-

the benefits of coordinating absolute time (insofar jobs take consistent amount of time) output ready others @ time (e.g. update dashboard during night people see in morning).

the benefits of coordinating relative frequency that, if oozie (or it's server) down, no jobs skipped (e.g. daily job might run 2 hours late, not 22 hours late).

how can like:

start="2009-01-01t21:00z" frequency="${coord:days(1)}" run-if-skipped="true"

i.e. when all's well, jobs run daily @ 9pm. if happens oozie (e.g. server rolled) between 8pm , 10pm, once oozie comes @ 10pm, job should run @ 10pm, , tomorrow @ 9pm normal.

not sure understand question.

if server down, , re-start coordinator, start coordinator start time.

also can make job run every hour, check if output folder exist - stop . use decision control node

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
