-------------------------------------------------------------------
Added a patch with fix to allow creation of types even when
updateTypeDefinition is set to false.
As there can be many types in the exported zip file ( which may / may not be
present in the backup cluster ) , it would be a little overhead to check if
type is already present and update if present.
Also , updateTypeDefinition's default value is true. So , if
updateTypeDefinition is set to true or not set at all , Atlas would still go
ahead and create/update the types.
Please let me know/re-assign if there is be a better way of fixing this.
Tested the patch with following :
1. updateTypeDefinition set to false
2. updateTypeDefinition set to true
3. updateTypeDefinition is not specified
4. updateTypeDefinition with true/false with other options such as transforms

> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 0.9-incubating, 0.8.1-incubating
> Reporter: Sharmadha Sainath
> Assignee: Sharmadha Sainath
> Priority: Critical
> Attachments: ATLAS-1970.patch, ImportFailureDueToUnknownType.txt
>
>
> Import has option "updateTypeDefinition" which is used to update the type
> definitions in the backup cluster (cluster on which import is done) when the
> value is set to true. (Default is set to true). When its value is set to
> false , types in backup cluster are not updated with types present in
> exported zip file.
> This works fine when , say a type type1 is present in both clusters , an
> entity of type type1 is exported and imported into backup cluster with
> updateTypeDefinition is set to false - Import is done successfully and type
> is not updated.
> When the zip file contains type5 *which is not present in backup cluster* and
> the when import is fired , import fails with following exception:
> {code}
> {"errorCode":"ATLAS-500-00-001","errorMessage":"org.apache.atlas.exception.AtlasBaseException:
> Type ENTITY with name type5 does not exist"}
> {code}
> Attached the complete exception stack trace found in backup cluster's
> application logs.
