------------------------------
Summary: Server early terminate when zookeeper singa folder is not
initially empty
Key: SINGA-5
URL: https://issues.apache.org/jira/browse/SINGA-5
Project: Singa
Issue Type: Bug
Reporter: Sheng Wang
Ideally, when a singa process crashes, its registered (ephemeral) file in
zookeeper will be automatically deleted.
However, this deletion will be executed after a TIME_OUT time. Hence, if we
rerun singa immediately, the server will get a phantom worker. If this is the
only registered worker when the file is finally deleted, the server will think
all workers have been left. It may terminate its service, before worker starts
to execute.
