getImpalaQueryAttributes

ApiImpalaQueryAttributeList getImpalaQueryAttributes(clusterName, serviceName)

Returns the list of all attributes that the Service Monitor can associate with Impala queries.

Examples of attributes include the user who issued the query and the number of HDFS bytes read by the query.

These attributes can be used to search for specific Impala queries through the getImpalaQueries API. For example the 'user' attribute could be used in the search 'user = root'. If the attribute is numeric it can also be used as a metric in a tsquery (ie, 'select hdfs_bytes_read from IMPALA_QUERIES').

Note that this response is identical for all Impala services.

Available since API v6.
