----------------------------------
Summary: Solr start scripts -- only log to console when running in
foreground
Key: SOLR-8186
URL: https://issues.apache.org/jira/browse/SOLR-8186
Project: Solr
Issue Type: Improvement
Components: scripts and tools
Affects Versions: 5.3.1
Reporter: Shawn Heisey
Currently the log4j.properties file logs to the console, and the start scripts
capture console output to a logfile that never rotates. This can fill up the
disk, and when the logfile is removed, the user might be alarmed by the way
their memory statistics behave -- the "cached" memory might have a sudden and
very large drop, making it appear to a novice that the huge logfile was hogging
their memory.
The logfile created by log4j is rotated when it gets big enough, so that
logfile is unlikely to fill up the disk.
I propose that we copy the current log4j.properties file to something like
log4j-foreground.properties, remove CONSOLE logging in the log4j.properties
file, and have the start script use the alternate config file when running in
the foreground. This way users will see the logging output when running in the
foreground, but it will be absent when running normally.
