Subject custom master service can not stop
Date Thu, 29 Mar 2018 12:14:47 GMT
Hi! 

I add a master service as below: 

<schemaVersion>2.0</schemaVersion> 
<services> 
<service> 
<name>YUM</name> 
<displayName>YUM</displayName> 
<comment>Yum Service</comment> 
<version>1.0.0</version> 
<components> 
<component> 
<name>YUM_MASTER</name> 
<displayName>Yum Master</displayName> 
<category>MASTER</category> 
<cardinality>1</cardinality> 
<commandScript> 
<script>scripts/master.py</script> 
<scriptType>PYTHON</scriptType> 
<timeout>600</timeout> 
</commandScript> 
</component> 
<component> 
<name>YUM_SLAVE</name> 
<displayName>Yum Slave</displayName> 
<category>SLAVE</category> 
<cardinality>1+</cardinality> 
<commandScript> 
<script>scripts/slave.py</script> 
<scriptType>PYTHON</scriptType> 
<timeout>600</timeout> 
</commandScript> 
</component> 
</components> 
<osSpecifics> 
<osSpecific> 
<osFamily>any</osFamily> 
</osSpecific> 
</osSpecifics> 
</service> 
</services> 
</metainfo> 

master.py: 

class Master(Script): 
def install(self, env): 
print 'Install Yum' 

def start(self, env): 
print 'Start Yum' 

def stop(self, env): 
print 'Stop Yum' 

def status(self, env): 
print 'Test Yum' 

if __name__ == "__main__": 
Master().execute() 

slave.py: 

class Slave(Script): 
def install(self, env): 
print 'Wait for Yum_Master install finish...' 

def start(self, env): 
print 'Wait for Yum_Master install finish...' 

def stop(self, env): 
print 'Wait for Yum_Master stop finish...' 

def status(self, env): 
print 'Wait for Yum_Master test finish...' 

if __name__ == "__main__": 
Slave().execute() 

I install it successfully, but when stop on the web UI, the master can not stop: 

Test Yum 
Test Yum 
Test Yum 
Test Yum 
Test Yum 
Test Yum 
Test Yum 
Test Yum 
Test Yum 
2018-03-29 19:12:54,068 - Waiting for actual component stop 

It hang at 35%. 

I follow https://cwiki.apache.org/confluence/display/AMBARI/Defining+a+Custom+Service, did
i miss something import? 

Best wishes
