Madhan Neethiraj commented on ATLAS-2120:
-----------------------------------------
bq. Entity is not imported into the cluster2 , but the type definition of tag1
in cluster2 had 3 attributes now (attrib1 : date , attrib2:Integer ,
attrib3:Integer)
[~ashutoshm] - import should have failed with no updates to tag1 definition,
right? i.e attrib2 shouldn't have been added to tag1 in cluster2.
> Inconsistency in Importing already existing types on backup cluster with new
> definition.

> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 0.9-incubating
> Reporter: Sharmadha Sainath

> 1.Created a tag tag1 on cluster1 with attributes :
> * attrib1 : string
> * attrib2 : integer
> 2.Created a tag with same name on cluster2 with attributes:
> * attrib1: date
> * attrib3: integer
> (Note the tag names are same , and attrib1 is same but datatypes of attrib1
> are different in both the clusters)
> 3. On cluster1 , created an entity and associated the tag1 to the entity with
> attribute values
> * attrib1: "randstr"
> * attrib2: 5
> and exported the entity into zip file .
> 4.Tried to import the entity into cluster2.
> Import failed with 500 Internal server error and with following exception :
> {code}
> {"errorCode":"ATLAS-500-00-001","errorMessage":"org.apache.atlas.exception.AtlasBaseException:
> org.apache.atlas.repository.graphdb.AtlasSchemaViolationException:
> com.thinkaurelius.titan.core.SchemaViolationException: Value [rand_str] is
> not an instance of the expected data type for property key [tag1.attrib1] and
> cannot be converted. Expected: class java.lang.Long, found: class
> java.lang.String"}
> {code}
> Following is the inconsistency observed :
> Entity is not imported into the cluster2 , but the type definition of tag1 in
> cluster2 had 3 attributes now (attrib1 : date , attrib2:Integer ,
> attrib3:Integer) and 500 Internal server error is thrown.
> Normally, when a datatype of an attribute is attempted to be updated , Atlas
> throws the following exception and the type is not updated.
> {code}
> {"errorCode":"ATLAS-400-00-029","errorMessage":"Data type update for
> attribute is not supported"}
> {code}
> Expected the same to happen while importing (i.e) Import failing with Bad
> request with the proper error message.
