How can i configure this from coordinator or workflow ? my bundle : <?xml version="1.0" encoding="UTF-8"?> <bundle-app name="ods-jobs-bundle" xmlns="uri:oozie:bundle:0.2"> <controls> <kick-off-time>${kickOffTime}</kick-off-time> </controls> <coordinator name="ods-ds-cms-coordinator" > <app-path>${exampleDir}/ods-ds-cms-coordinator.xml</app-path> </coordinator> </bundle-app> coordinator : <coordinator-app name="ods-ds-cms-coordinator" start="${startTime}" end="${endTime}" frequency="60" timezone="${timeZone}" xmlns="uri:oozie:coordinator:0.4"> <action> <workflow> <app-path>${exampleDir}/ods-ds-cms-workflow.workflow</app-path> <configuration> <property> <name>nameNode</name> <value>${nameNode}</value> </property> <property> <name>jobTracker</name> <value>${jobTracker}</value> </property> <property> <name>exampleDir</name> <value>${nameNode}/custom/oozie</value> </property> </configuration> </workflow> </action> </coordinator-app> workflow 1: <?xml version="1.0" encoding="UTF-8"?> <workflow-app xmlns="uri:oozie:workflow:0.5" name="ods-ds-cms-workflow.workflow"> <global> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <configuration> <property> <name>mapred.job.queue.name</name> <value>${queue}</value> </property> </configuration> </global> <start to="cms-checker"/> <action name="cms-checker"> <java> <main-class>com.insense.helper.CMSPullChecker</main-class> <arg>${cmsChecker}</arg> <arg>${cmsType}</arg> <capture-output/> </java> <ok to="trigger_next_job"/> <error to="kill"/> </action> <!-- need to triger this task after 45 minutes of previous task --> <action name="trigger_next_job"> <sub-workflow> <app-path>${exampleDir}/ods-next-task.workflow</app-path> <propagate-configuration/> </sub-workflow> <ok to="end"/> <error to="kill"/> </action> <kill name="kill"> <message>Something went wrong in ods-workflow</message> </kill> <end name="end"/> </workflow-app> workflow 2: <?xml version="1.0" encoding="UTF-8"?> <workflow-app xmlns="uri:oozie:workflow:0.5" name="ods-next-task.workflow"> <global> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <configuration> <property> <name>mapred.job.queue.name</name> <value>${queue}</value> </property> </configuration> </global> <start to="campaign-customer-eligibility-mr"/> <action name="campaign-customer-eligibility-mr"> <java> <main-class>com.insense.MyMapReduceJobDriver</main-class> <capture-output/> </java> <ok to="done"/> <error to="kill"/> </action> <kill name="kill"> <message>Something went wrong in ods-workflow</message> </kill> <end name="done"/> </workflow-app> How can I do this from oozie coordinator or workflow . I can do some thing like java action with Thread.sleep(45 * 60* 1000) but don't wanted to do this . Thanks ... View more
