Joel Bernstein created SOLR-7472:
------------------------------------
Summary: SortingResponseWriter does not log fl parameters that
don't exist.
Key: SOLR-7472
URL: https://issues.apache.org/jira/browse/SOLR-7472
Project: Solr
Issue Type: Bug
Affects Versions: 5.1, 5.0, 4.10.4, 4.10.2, 4.10.1, 4.10, 4.9.1, 4.9
Reporter: Joel Bernstein
Fix For: 5.2
The SortingResponseWriter, which is the response writer for the /export
handler, does not log the error that is thrown when an fl is specified that
does not exist.
The reason for this is that an unchecked SolrException is being thrown from the
IndexSchema. All other exceptions in SortingResponseWriter are wrapped in an
IOException.
For reasons I'm not entirely sure of the ResponseUtils class doesn't log the
stacktrace for errors with codes between 500 and 100. It considers these to be
normal error conditions. So the unchecked SolrException was not being logged.
The short term fix for this is to catch the exception from the IndexSchema and
wrap it in a IOException like the other exceptions from the
SortingResponseWriter.
Longer term I think it makes sense to review the ResponseUtil exception logging
logic.
