Subject [jira] [Commented] (ATLAS-135) Re-model hive type system
Date Fri, 16 Oct 2015 19:38:05 GMT


Shwetha G S commented on ATLAS-135:

>From HiveMetaStoreBridge.createTableInstance()
        tableRef.set("createTime", hiveTable.getMetadata().getProperty(hive_metastoreConstants.DDL_TIME));
        tableRef.set(HiveDataModelGenerator.COMMENT, hiveTable.getParameters().get(HiveDataModelGenerator.COMMENT));

Some of the important properties(like createTime, comment) are stored as map<string, string>
in hive metastore. They are mapped as is in the hive model. Instead, they should be exposed
as first class attributes in hive model so that users can get/search for them in atlas

> As of now, hive model looks like copy of hive metastore schema. For example, some important
info like table type is part of parameters which is map<string, string>. We should re-model
this to make search easier
