--------------------------------------
Summary: Zeppelin does not kill some interpreters when server is
stopped
Key: ZEPPELIN-79
URL: https://issues.apache.org/jira/browse/ZEPPELIN-79
Project: Zeppelin
Issue Type: Bug
Components: Core
Affects Versions: 0.5.0
Reporter: Jonathan Kelly
Fix For: 0.5.0
When the Zeppelin server is stopped (e.g., with a SIGTERM), it should also stop
all interpreter processes that it has started. Instead, I sometimes see them
hang around as orphaned children after the Zeppelin server has stopped. This
seems to be the case with the spark interpreter (at least with yarn-client
mode; haven't tested with standalone or local modes) and with the shell
interpreter. It does not seem to occur with the hive or angular interpreters;
those ones stop when the server is stopped.
