László Bodor updated HIVE-25107:
--------------------------------
Description:
This is since HIVE-21584
I have a *72M* llap executor log file, then I grepped for only "thread class
path", piped into a separate file and a result was a *22M* file...1/3-1/4 of
the file was classpath info which is not usable for most of the time. This
overwhelming amount of classpath info is not needed, assuming that classpath
issues are reproducible with more or less effort, user should be responsible
for turning on this expensive logging on demand. Not to mention performance
implications which cannot be ignored beyond a certain amount of log messages.
