public ZkProcessorLatch(int size, String latchId, String participantId, ZkUtils zkUtils) {
 this.zkUtils = zkUtils;
 this.participantId = participantId;
 ZkKeyBuilder keyBuilder = this.zkUtils.getKeyBuilder();
 latchPath = String.format("%s/%s", keyBuilder.getRootPath(), LATCH_PATH + "_" + latchId);
 // TODO: Verify that validatePaths doesn't fail with exceptions
 zkUtils.validatePaths(new String[] {latchPath});
 targetPath =  String.format("%s/%010d", latchPath, size - 1);
 LOG.debug("ZkProcessorLatch targetPath " + targetPath);
}
