Accessing Metadata

Searching Metadata

1. Start and log into the Cloudera Navigator data management component UI.
2. Do one of the following:
   • Type a search string into the Search box that conforms to the search syntax and press Return or Enter.
   • Click the Click here link.
   The Search page displays. It has a Search box and two panes: the Filters pane and the Search Results pane.

To display all entities, click Clear all filters and press Return or Enter. You filter the search results by specifying filters or typing search strings in the Search box.

Search Results

The Search Results pane displays the number of matching entries in pages listing 25 entities per page. You can view the pages using the page control at the bottom of each page.

Displaying Entity Details

If managed properties have been defined for a particular entity type, the Show All checkbox in the Managed Metadata pane displays all properties that can be assigned values for the selected entity. To display only those properties that have values, deselect the checkbox. If all properties have values, the checkbox has no effect.

To display entity details:

1. Perform a search.
2. In the search results, click an entity name link. The Details tab displays.

Filtering Search Results

To filter search results, specify filters in the Filters pane or type search strings in the Search box.

The Filters pane contains a set of default properties (source type, type, owner, cluster, and tags) and property values (also referred to as facets). You can add a filter by clicking in Add Another Filter... or by typing in the filter combo box to search for it (additionally use the up and down keys) and pressing Return or Enter on the selected filter.

As you add filters, filter breadcrumbs are added between Search box and search results, and search results are refreshed immediately. Multiple filters composed with the + operator are separated with the | character.

To remove non-default filter properties, click the in the filter.

Specify a property value as follows:

• Boolean - Select the option to respectively not display, or display only those entries, with the value set to true: Do not show XXX (the default) or Show XXX only, where XXX is the Boolean property.
• Enumerated or freeform string
  • Select the checkbox next to a value or click a value link.
  • If a property has no values, click add a new value, click the text box, and select from the populated values in the drop-down list or type a value.
• Timestamp - Timestamps are used for started, ended, created, last accessed, and last modified properties. The server stores the timestamp in UTC, and the UI displays the timestamp converted to the local timezone. Select one of the timestamp options:
  • A Last XXX day(s) link.
  • The Last checkbox, type or specify the value using the spinner control and select the unit minutes, hours, or days.
  • The Custom period checkbox and specify the start and end date.
    • Date - Click the down arrow to display a calendar and select a date, or click a field and click the spinner arrows or up and down arrow keys.
    • Time - Click the hour, minute, and AM/PM fields and click the spinner arrows or up and down arrow keys to specify the value.
    • Move between fields by clicking fields or by using the right and left arrow keys.

To remove filter values, click the in the breadcrumb or deselect the checkbox.

When you select a specific source type value, additional properties that apply to that source type display. For example, HDFS has size, created, and group properties:

The number in parentheses (facet count) after a property value is the number of extracted entities that have that property value:

When you type values, the value is enclosed in quotes; the value inside the quotes must exactly match the metadata. For example, typing "sample_*" in the originalName property returns only entities whose names match that exact string. To perform a wildcard search, type the wildcard string in the Search box. For example, typing the string "sample_*" in the Search box returns all entities with "sample_" at the beginning of their original name.

+(sourceType:hdfs sourceType:hive) +(type:file type:directory)

 ((+sourceType:hdfs +created:[NOW/DAY-30DAYS TO NOW/DAY+1DAY]) sourceType:hive)
