Marcel Reutegger created SLING-4899:
---------------------------------------
Summary: Background servlet not cluster aware
Key: SLING-4899
URL: https://issues.apache.org/jira/browse/SLING-4899
Project: Sling
Issue Type: Bug
Components: Extensions
Affects Versions: Background Servlets 1.0.0
Reporter: Marcel Reutegger
The background servlet creates stream nodes under a configurable path with a
local counter. When running in a cluster, it may happen that background
servlets on multiple cluster nodes try to create the same stream node.

java.lang.IllegalArgumentException: Stream node already exists:
/var/bg/jobs/2015/07/17/15/51/82/stream
at
org.apache.sling.bgservlets.impl.storage.JobDataImpl.getOutputStream(JobDataImpl.java:74)
at org.apache.sling.bgservlets.impl.BackgroundRequestExecutionJob.<init>
{noformat}
It would probably be good to include the slingId in the path prefix to separate
streams from different cluster nodes. A similar approach is implemented already
for sling jobs.
