>
> As part of SENTRY-1931, we added check not to send two NN snaphsots at the
> same time. But because of a conditional typo, it results in sending back two
> snapshots.
> {code}
> // If another paths updates request is in progress by another HDFS
> NameNode, then we
> // return an empty image for now to avoid a large memory consumption
> if (pathsRetrieverBusy.compareAndSet(false, true)) {
> LOGGER.debug("PATHS updates are not available because another request
> is in progress.");
> return Collections.emptyList();
> }
> {code}
