[jira] [Commented] (OOZIE-1042) Coordinator action table schema
change
[ https://issues.apache.org/jira/browse/OOZIE-1042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13486713#comment-13486713 ]
Mohammad Kamrul Islam commented on OOZIE-1042:
----------------------------------------------
Create a new column called Push_missingDependency of type BLOB in table COORD_ACTIONS. Needs to modify CoorinatorAction and JsonCoordinatorAction class.
There will be two columns to identify two different dependencies.
1. Missing dependencies (existing): Only those dependency that needs polling. Such as : directory based dependencies.
2. Push Missing dependencies: Dependencies that rely on the push model where some messaging system will inform when new data is available. For example, partition-based dependencies provided by hcatalog.
