Key: PIO-201
URL: https://issues.apache.org/jira/browse/PIO-201
Project: PredictionIO
Issue Type: Bug
Affects Versions: 0.13.0
Environment: spark ubuntu
Reporter: WangShiXin
After i trained on cluster A got log like：
{quote}[INFO] [Engine$] EngineWorkflow.train completed
[INFO] [Engine] engineInstanceId=8e334d55-1482-4d79-9b55-e02b91aa0caa

then, when deploy on server B use pio deploy,failed:
{quote}[WARN] [Template$] /home/dev/tmp/deploy/template.json does not exist.
Template metadata will not be available. (This is safe to ignore if you are not
working on a template.)

identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+

explicit option isn't set. For compliance with existing applications not using
SSL the verifyServerCertificate property is set to 'false'. You need either to
explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide
truststore for server certificate verification.

Try running 'train' before 'deploy'. Aborting.

When I specify --engine-instance-id with the engineInstanceId got from tail of
the train log, it work well.
Now I have to manually copy engineInstanceId from cluster A's log and redeploy
with engineInstanceId I got when update model.
This issue did'n appear when train/deploy both run in same server.
