Madhan Neethiraj updated ATLAS-1889: ------------------------------------ Fix Version/s: (was: trunk) > Failure in simultaneous updates to an entity tag association > ------------------------------------------------------------ > > Key: ATLAS-1889 > URL: https://issues.apache.org/jira/browse/ATLAS-1889 > Project: Atlas > Issue Type: Bug > Components: atlas-core > Affects Versions: 0.8-incubating > Reporter: Ashutosh Mestry > Assignee: Ashutosh Mestry > Priority: Major > Fix For: 0.8.1 > > Attachments: ATLAS-1889-Handling-multiple-entities.patch > > > *Background* > When multiple requests simultaneously attempt to change the tags associated > with an entity, the current implementation might result in APIs returning > fewer tags for the entity than is actually associated. > The problem thus causes UI not to behave correctly. > > *Solution* > Implements a synchronization mechanism. > > Steps to duplicate the problem: > * Create several tags. Eg. tag1, tag2, tag3, tag4. > * Attach these tags to and entity say ‘testtable1’ > * Use the following CURL commands to delete the tags: > {code} > curl -X DELETE -u admin:admin > 'http://localhost:21000/api/atlas/entities/a2d0b023-aafe-4ddd-bb90-65164af8796c/traits/tag1' > -H 'Content-Type: application/json' & > curl -X DELETE -u admin:admin > 'http://localhost:21000/api/atlas/entities/a2d0b023-aafe-4ddd-bb90-65164af8796c/traits/tag2' > -H 'Content-Type: application/json' & > curl -X DELETE -u admin:admin > 'http://localhost:21000/api/atlas/entities/a2d0b023-aafe-4ddd-bb90-65164af8796c/traits/tag3' > -H 'Content-Type: application/json' & > curl -X DELETE -u admin:admin > 'http://localhost:21000/api/atlas/entities/a2d0b023-aafe-4ddd-bb90-65164af8796c/traits/tag4' > -H 'Content-Type: application/json' > {code} > You will notice that entity _testtable1_ ends up with some tags not deleted. > Additional querying with gremlin will show that the edges are deleted > correctly. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
