Jonathan Hurley commented on AMBARI-6890:
-----------------------------------------
Example of an {{AlertDefinitionCommand}} with no definitions for this host:
{code}
{
'alertDefinitionCommands':[
{
'alertDefinitions':[ ],
'clusterName':'c1',
'commandType':'ALERT_DEFINITION_COMMAND',
'hash':'37a6259cc0c1dae299a7866489dff0bd',
'hostName':'c6404.ambari.apache.org'
}
]
}
{code}
Note that {{37a6259cc0c1dae299a7866489dff0bd}} represnts the NULL MD5 hash.
