DECOMMISSION BACKEND 问题
大家好，打扰了，
我用ALTER SYSTEM DECOMMISSION BACKEND 语句，尝试删除一个BE。
执行后，发现TabletNum并未减少，为75，SystemDecommissioned是true，LastHeartbeat这个指标也一直在更新
查看SHOW PROC '/statistic',发现有UnhealthyTabletNum为75。
尝试 用ALTER SYSTEM DROP BACKEND删除，提示errCode = 2, detailMessage = It is highly NOT RECOMMENDED to use DROP BACKEND stmt.It is not safe to directly drop a backend. All data on this backend will be discarded permanently. If you insist, use DROPP BACKEND stmt (double P).
是不是哪里出错了？
我改怎么排查UnhealthyTablet？
受影响的数据表以后还正常吗？
