Workflow ReRrun

Configs

  • oozie.wf.application.path
* Only one of following two configurations is mandatory. Both should not be defined at the same time
    • oozie.wf.rerun.skip.nodes
    • oozie.wf.rerun.failnodes
  • Skip nodes are comma separated list of action names. They can be any action nodes including decision node.
  • The valid value of oozie.wf.rerun.failnodes is true or false.
  • If secured hadoop version is used, the following two properties needs to be specified as well
    • mapreduce.jobtracker.kerberos.principal
    • dfs.namenode.kerberos.principal.
  • Configurations can be passed as -D param.
$ oozie job -oozie http://localhost:11000/oozie -rerun 14-20090525161321-oozie-joe -Doozie.wf.rerun.skip.nodes=<>

Pre-Conditions

  • Workflow with id wfId should exist.
  • Workflow with id wfId should be in SUCCEEDED/KILLED/FAILED.
  • If specified , nodes in the config oozie.wf.rerun.skip.nodes must be completed successfully.

ReRun

  • Reloads the configs.
  • If no configuration is passed, existing coordinator/workflow configuration will be used. If configuration is passed then, it will be merged with existing workflow configuration. Input configuration will take the precedence.
  • Currently there is no way to remove an existing configuration but only override by passing a different value in the input configuration.
  • Creates a new Workflow Instance with the same wfId.
  • Deletes the actions that are not skipped from the DB and copies data from old Workflow Instance to new one for skipped actions.
  • Action handler will skip the nodes given in the config with the same exit transition as before.
