Review Comment:
   Maybe we could make use of 
https://github.com/apache/doris/blob/2dddab03a1a0c73325159c31f5c23653ad63f69c/fe/fe-core/src/main/java/org/apache/doris/system/SystemInfoService.java#L368-L383
 
   to check alive BE and no need to ping here.

Review Comment:
   Moreover, I think we could treat `!ok` as timeout, and 
`!countDownLatch.getStatus().ok()` as BE down.
