Monani Mihir updated HBASE-20701:
---------------------------------
Description:
When balancer runs, it tries to find least loaded server with better locality
for current region. During this, we make debug level logging for each of those
regions. It creates too much amount of logging at debug level , we should move
this to trace level logging.
{code:java}
int getLeastLoadedTopServerForRegion (int region, int currentServer) {
...
if (leastLoadedServerIndex != -1) {
LOG.debug("Pick the least loaded server " +
servers[leastLoadedServerIndex].getHostname()
+ " with better locality for region " + regions[region]);
}
...
}{code}
