----------------------------------
Summary: Change multilang heartbeat mechanism to multi-threading
of subprocess
Key: STORM-871
URL: https://issues.apache.org/jira/browse/STORM-871
Project: Apache Storm
Issue Type: Improvement
Reporter: Jungtaek Lim
Having design constraint of multilang heartbeat, some issues are raised at the
moment.
(https://issues.apache.org/jira/browse/STORM-738 is a kind of reporting)
I'm trying to add workarounds (https://issues.apache.org/jira/browse/STORM-742
and so on), but if we can get rid of design constraint it would be really great.
Maybe we can use pid file of subprocess (subprocess write it from sendpid()) to
check subprocess heartbeat from ShellSpout / ShellBolt.
Letting subprocess launch new thread which writes pid file periodically, to
make sure "modified time" of file is periodically up to date. (It is just an
idea, and it should be validated.)
