Hi,
I have cm_api scripts that create a multinode cdh cluster, which is working
fine.
I have another script that adds new hosts to the cluster and apply a
template, but this fails with the below error. Not sure if I am missing
something.
Note: From the UI I can apply the same template to the host and it works
fine, but not from the cm_api
datanode_template = None
try:
datanode_template = cluster.get_host_template(template_name)
except ApiException, ex:
LOG.critical('No template by name %s found. Please verify the
template name' %(template_name))
raise(ex)
cmd = datanode_template.apply_host_template(host_ids=host_list,
start_roles=False) # Fails here
if not cmd.wait(CM_START_TIMEOUT).success:
LOG.warn('Failed to apply template to datanodes')
LOG.warn('Command message: %s' %(cmd.resultMessage))
else:
LOG.info('Template %s applied to datanodes sucessfully and started'%(template_name))
Exception message on the console:
