zhangqianqiong updated HDFS-14548:
----------------------------------
    Description: 
when a new snapshot is created, the snapshotCounter would increment, but when a 
snapshot is deleted, the snapshotCounter would not decrement. Over time, when 
the snapshotCounter reaches the MaxSnapshotID, the new snapshot cannot be 
created.

By the way, How can I reset the snapshotCounter?
