Example 12 with AzureException

use of org.apache.samza.AzureException in project samza by apache.

the class TableUtils method deleteProcessorEntity.

 * then the delete operation will fail.

 * @param jmVersion Job model version of the processor row to be deleted.
 * @param pid Unique processor ID of the processor row to be deleted.
 * @param force True, to disable optimistic locking on the table. False, otherwise. Setting to false may result in
 *              AzureException when there is concurrent access to the table.
 *
 * @throws AzureException If an Azure storage service error occurred.
