This is the test code
{code:title=visibility_labels_admin_test.rb}
label = 'TEST_VISIBILITY'
user = org.apache.hadoop.hbase.security.User.getCurrent().getName();
visibility_admin.add_labels(label)
visibility_admin.set_auths(user, label)
{code}
It says 'label does not exists' when calling set_auths.
Then I add some ugly logs in DefaultVisibilityLabelServiceImpl and VisibilityLabelsCache.
{code:title=DefaultVisibilityLabelServiceImpl.java}
public OperationStatus[] addLabels(List<byte[]> labels) throws IOException {
...
if (mutateLabelsRegion(puts, finalOpStatus)) {
updateZk(true);
}
for (byte[] label : labels) {
String labelStr = Bytes.toString(label);
LOG.info(labelStr + "=====" + this.labelsCache.getLabelOrdinal(labelStr));
}
...
}
{code}
{code:title=VisibilityLabelsCache.java}
public void refreshLabelsCache(byte[] data) throws IOException {
LOG.info("========refresh", new Exception());
...
}
{code}
And I modified TestVisibilityLabelsWithCustomVisLabService to use DefaultVisibilityLabelServiceImpl, then collected the logs of setupBeforeClass

We can see that, refresh is triggered from a background zk watcher, and it is possible that the labels are not in labelsCache after addLabels being called.
