There is RegionNormalizerTracker which tracks region normalizer state up in
ZK.
When user toggles normalizer switch through shell, the following method
in MasterRpcServices is called:
public boolean normalizerSwitch(boolean on) {
boolean oldValue = master.getRegionNormalizerTracker().isNormalizerOn();
...
master.getRegionNormalizerTracker().setNormalizerOn(newValue);
In RegionNormalizerTracker :
public boolean isNormalizerOn() {
byte [] upData = super.getData(false);
try {
// if data in ZK is null, use default of on.
return upData == null || parseFrom(upData).getNormalizerOn();
So I guess the config parameter hbase.normalizer.enabled can be dropped.
Cheers
