--------------------------------
Summary: Stamp core names on log entries for certain classes
Key: SOLR-5277
URL: https://issues.apache.org/jira/browse/SOLR-5277
Project: Solr
Issue Type: Bug
Components: search, update
Affects Versions: 4.4, 4.3.1, 4.5
Reporter: Dmitry Kan
It is handy that certain Java classes stamp a [coreName] on a log entry. It
would be useful for multicore setup if more classes would stamp this
information.
In particular we came accross a situaion with commits coming in a quick
succession to the same multicore shard and found it to be hard time figuring
out was it the same core or different cores.
The classes in question with log sample output:
