hadoop - Oozie Workflow EL function timestamp() does not give seconds -


i have following oozie workflow:

<workflow-app name="${workflow_name}" xmlns="uri:oozie:workflow:0.4">      <global>         <job-tracker>${jobtracker}</job-tracker>         <name-node>${namenode}</name-node>         <configuration>             <property>                 <name>mapred.job.queue.name</name>                 <value>${launcherqueuename}</value>             </property>             <property>                 <name>mapred.queue.name</name>                 <value>${launcherqueuename}</value>             </property>         </configuration>     </global>      <start to="email-1" />      <action name="email-1">         <email xmlns="uri:oozie:email-action:0.1">             <to>${toemaillist}</to>             <cc>${ccemaillist}</cc>             <subject>ts</subject>             <body>                  timestamp:  ${timestamp()}             </body>         </email>          <ok to="mail-2" />         <error to="kill-fail" />     </action>  ... 4 more actions mail-2, mail-3 , mail-4      <kill name="kill-fail">         <message>${workflow_name} failed, error             message[${wf:errormessage(wf:lasterrornode())}]         </message>     </kill>      <end name="end" /> </workflow-app>

the emails have timestamp values as

timestamp:  2016-01-27t16:19z

accoring el definition, should in format: (yyyy-mm-ddthh:mm:ss.sz

why not getting seconds?

what trying do: trying figure out if these 4 function calls return same value or different values. need not change , if timestamp() doesnt work me, want consider coordinator's nominaltime / actualtime el functions.

if cant seconds in timestamp, there way pause each action allow them execute across time range of more 1 minute?

edit: summarizing answers below samson scharfrichter:

1) why there no seconds in timestamp() ?

previous versions had seconds version 4.2 not.

2) there function can give me seconds well?

afaik no

3) how use same time value in actions of workflow?

pass coord:nominaltime() property coordinator , use multiple times in actions.

4) how make action pause in workflow?

thre no simple way. use java action - jar simple class thread.sleep()

quoting oozie documentation v4.2

4.2.2 basic el functions

string timestamp()

it returns current datetime in iso8601 format, down minutes (yyyy-mm-ddthh:mmz), in oozie's processing timezone, i.e. 1997-07-16t19:20z

that seems pretty consistent get.

you can format coord:nominaltime() down second if wish, in coordinator -- therefore must stuff result <configuration> property forward workflow script.

and afaik coord:actualtime() refers non-deterministic time, in past, when coordinator started think next workflow instance. can't imagine can used for.

by way, don't "what [you] trying do" ; if want generate unique ids actions, have many ways without relying on fact oozie slow , not execute multiple actions in same second.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
