Yu Li commented on HBASE-21777:
-------------------------------
Maybe combining both is a better idea, please let me know how you feel about
the following sample:
{code}
if (LOG.isDebugEnabled()) {
if (maxThroughputToSet != getMaxThroughput()) {
LOG.debug("CompactionPressure is " + compactionPressure + ", tune
throughput to "
+ throughputDesc(maxThroughputToSet));
} else if (LOG.isTraceEnabled()) {
LOG.trace("CompactionPressure is " + compactionPressure + ", keep
throughput throttling to "
+ throughputDesc(maxThroughputToSet));
}
}
{code}
Thanks.
