Xinyu Tan updated RATIS-1786:
-----------------------------
Description: Digester of the Follower only calls `digester.get().digest()`
to get an MD5 and reset the engine when a file is completed. However, if the
client does not complete the file transmission when the streaming time expires,
digester is not reset during subsequent snapshot transfers. Therefore, a
different md5 value is calculated, causing the installSnapshot to fail forever.
