Kihwal Lee commented on HDFS-7706:
----------------------------------
Can we also convert log statements to use "{ }" in order to avoid unnecessary
string constructions? Profiling has shown that when {{blockStateChangeLog}}
log level is set to WARN, significant time is still spent in constructing and
garbage collecting log message strings for the INFO level messages.
> Switch BlockManager logging to use slf4j
