 FE may fail to start bdbje and synchronize between FEs for some reasons. Phenomena include the inability to write metadata, the absence of MASTER, and so on. At this point, we need to manually restore the FE. The general principle of manual recovery of FE is to start a new MASTER through metadata in the current `meta_dir`, and then add other FEs one by one. Please follow the following steps strictly:
 
-1. First, stop all FE processes and all business access. Make sure that during metadata recovery, external access will not lead to other unexpected problems.

 2. Identify which FE node's metadata is up-to-date:

 FE 有可能因为某些原因出现无法启动 bdbje、FE 之间无法同步等问题。现象包括无法进行元数据写操作、没有 MASTER 等等。这时，我们需要手动操作来恢复 FE。手动恢复 FE 的大致原理，是先通过当前 `meta_dir` 中的元数据，启动一个新的 MASTER，然后再逐台添加其他 FE。请严格按照如下步骤操作：
 
-1. 首先，停止所有 FE 进程，同时停止一切业务访问。保证在元数据恢复期间，不会因为外部访问导致其他不可预期的问题。
