A Hadoop cluster can contain thousands of entities, and different entities can have similar names. To find a Cloudera entity in Metadata Manager, you can navigate the metadata catalog or you can search for the object by name or identity. The method that you select depends on the number of objects that are likely to have similar names.
Use the following methods to find a Cloudera entity in Metadata Manager:
Navigate the metadata catalog.
Metadata Manager creates a parent group in the metadata catalog for each entity type that it extracts from Cloudera Navigator. To find an entity, open its parent group, and scroll down to the entity.
Search by name.
Use the keyword or advanced search in Metadata Manager to search for the entity by name. Escape any special character in the entity name with a backslash (
\
).
For example, to search for YARN job template
select * from emp_07 where salary > 50000(Stage
, enter the following search string:
select \* from emp_07 where salary > 50000\(Stage
Metadata Manager returns all objects that match the search string.
Search by identity.
Use the keyword search in Metadata Manager to search for an entity by its Cloudera identity. Search by identity when many objects have similar names. When you search by identity, Metadata Manager returns the one metadata object with the identity value you specify.
To find the identity for an entity in Cloudera Navigator, download the lineage JSON file. Open the file in a text editor and find the entity. Copy the value of the identity property from the file and enter it in the
Search
field in Metadata Manager.
In Metadata Manager, you can view the identity value for a Cloudera metadata object in the
identity
property in the Details panel. To see all object properties, click
