      Description

      Since the client had a temporary network failure, After it recovered.
      I found my client thread was blocked.
      Looks below stack and logs, It said that we use a invalid CatalogTracker in function "tableExists".

      Block stack:

      In ZooKeeperNodeTracker, We don't throw the KeeperException to high level.
      So in CatalogTracker level, We think ZooKeeperNodeTracker start success and
      continue to process .
