Subject [jira] [Commented] (ATLAS-597) Handle Cluster renaming
Date Fri, 26 Aug 2016 07:59:21 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15438633#comment-15438633

Suma Shivaprasad commented on ATLAS-597:
----------------------------------------

Changes required in DSL search :

clusterName is also being used as a separate searchable attribute for asset search. This also
needs to be replaced with "clusterId". 
One question to consider is 
Should we continue to support search by clusterName . If this is required, then we will need
to treat cluster as a special entity, map clusterName to clusterId during gremlin translation.

> Cluster name could easily be changed by users which is used in qualified names to dedup
entities. For eg: hive_table has a qualifiedName <dbName.tableName@clusterName> . Hence
all entities will be recreated if they are renamed unless a migration on repository is done
with new cluster name.
> Hence cluster  should be represented by an id which is constant and tied to clusterName
which could change
