Review Comment:
do you think this is a better implementation of `getTableIDs()`:
```
@Override
public Set<TableId> getTableIDs() {
final String tablesPath = context.getZooKeeperRoot() + Constants.ZTABLES;
final ZooReader zr = context.getZooReader();
final Set<TableId> tids = new HashSet<>();
while (true) {
try {
zr.sync(tablesPath);
zr.getChildren(tablesPath).forEach(t -> tids.add(TableId.of(t)));
return tids;
} catch (KeeperException | InterruptedException e) {
log.error("Error getting tables from ZooKeeper, retrying", e);
UtilWaitThread.sleepUninterruptibly(1, TimeUnit.SECONDS);
continue;
}
}
}
```
