-------------------------------------
Summary: Print message when open file limit restricts size of file
handle cache
Key: IMPALA-7772
URL: https://issues.apache.org/jira/browse/IMPALA-7772
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 3.1.0
Reporter: Joe McDonnell
The size of the file handle cache is determined by the
min(max_cached_file_handles, OS limit on number of open files). Right now,
there is no message printed if the OS limit on the number of open files is less
than max_cached_file_handles. This is confusing, because the file handle cache
will be smaller than expected. We should print a message on startup in this
case.
