David Mollitor commented on HIVE-22607:
---------------------------------------
Put up patch that clears that name every time a session is closed so that if a
developer forgets to reset the thread name, it will be reset eventually. Patch
also so clean up, for example, the current code looks like it clears the name
from the front of the list only, but it's a bit ambiguous because it uses
'split' instead of subString to remove the front of the string. Changed it to
make it remove the session ID no matter where it is in the string so that it's
more clear and flexible.
