Modified APIs in 7.1.9
The following APIs have been modified for Oozie and include a description of the impact of the modifiaction on their use.
ActionExecutor.Context
Abstract method String[] getCallbackUrls(String) has been added to this interface.
- Package Name
- org.apache.oozie.action
- Effect
- Recompilation of a client program may be terminated with the message: a client class C is not abstract and does not override abstract method getCallbackUrls(String) in org.apache.oozie.action.ActionExecutor.Context.
- Reason for change
- Ability for Oozie to not rely on its LoadBalancer internally
- Recommendation
- Use the same implementation as ActionExecutorContext or return a single url wrapped into an array.
- Recompilation Required?
- Yes
ActionExecutor.Context
Abstract method FileSystem getFileSystemForDir(Path) has been added to this interface.
- Package Name
- org.apache.oozie.action
- Effect
- Recompilation of a client program may be terminated with the message: a client class C is not abstract and does not override abstract method getFileSystemForDir(Path) in org.apache.oozie.action.ActionExecutor.Context.
- Reason for change
- In order to make action dir base path configurable and Cloud FS ready
- Recommendation
- Use a similar implementation as ActionExecutorContext.
- Recompilation Required?
- Yes
JavaActionExecutor.setCredentialTokens
Access level has been changed from protected to package-private.
- Package Name
- org.apache.oozie.action.hadoop
- Effect
- Recompilation of a client program may be terminated with the message: setCredentialTokens(Credentials; Configuration; ActionExecutor.Context; WorkflowAction; MapString;CredentialsProperties) has package-private access in org.apache.oozie.action.hadoop.JavaActionExecutor.
- Reason for change
- Oozie to handle file-system credentials coming from various places
- Recommendation
- Users should not invoke this method in their own ActionExecutor implementation. If they absolutely need to invoke this, then their own ActionExecutor implementation should be in the org.apache.oozie.action.hadoop package.
- Recompilation Required?
- Yes
