Daniel Stieglitz updated NIFI-15531:
------------------------------------
Description:
Depending on different systems, it can take a few seconds for mapping
extensions but it is not clear in the logs what is happening. In the example
below There is ~40 seconds from when all the nar files have been expanded until
the first nar file is loaded.
{code:java}
2025-09-15 13:58:51,322 INFO [main] org.apache.nifi.nar.NarUnpacker Expanding
111 NAR files started
2025-09-15 13:59:19,783 INFO [main] org.apache.nifi.nar.NarUnpacker Expanded
111 NAR files in 28.461 seconds (28461014222 ns) 2025-09-15 13:59:59,298 INFO
[main] org.apache.nifi.nar.NarClassLoaders Loaded NAR file:
/home/someuser/nifi-2.6.0-SNAPSHOT/./work/nar/extensions/nifi-jetty-nar-2.6.0-SNAPSHOT.nar-unpacked
as class loader
{code}
The point of this ticket is to add another two log statements when the map
extensions starts and when it ends.
