> In one of integration test, I observed that a thread keeps spinning error
> logs "Unexpected exception handling blockUntilAvailable" due to
> KeeperException.ConnectionLossException. Below is the related code:
> {code}
> while (!finished) {
> try {
> data = ZKUtil.getData(zkw, znode);
> } catch(KeeperException e) {
> LOG.warn("Unexpected exception handling blockUntilAvailable", e);
> }
> if (data == null && (System.currentTimeMillis() +
> HConstants.SOCKET_RETRY_WAIT_MS < endTime)) {
> Thread.sleep(HConstants.SOCKET_RETRY_WAIT_MS);
> } else {
> finished = true;
> }
> }
> {code}
> ConnectionLossException might be recoverable but SessionExpiredException and
> AuthFailed are not recoverable errors, the while loop can't break.
