----------------------------------
Summary: Allow multiple instances to run on single host
Key: FLINK-2302
URL: https://issues.apache.org/jira/browse/FLINK-2302
Project: Flink
Issue Type: Bug
Components: Start-Stop Scripts
Affects Versions: 0.10
Reporter: Ufuk Celebi
Fix For: 0.10
The scripts currently can only run a single component like TaskManager per host.
The main reason is that there is a single PID file per running process (e.g.
TaskManager). If this file exists, no other process of the respective type can
be started. Instead of having a single file per process with a single PID, we
can append multiple PIDs to one file, e.g. a {{tm.pid}} can look like:
{code}
pid tm1
pid tm2
{code}
Stopping a TM then removes a single PID in FIFO fashion (add pids at tail,
remove pids from head).
