nodemanager异常 org.fusesource.leveldbjni.internal.NativeDB$DBException: Corruption: checksum mismatch

系统环境：ubuntu14.04 server cloudera CDH 5.10 共计28个节点。单节点内存128G。有6台机器是24核，22台机器是32核。有10台机器磁盘容量是1.8T 18台机器磁盘容量是12.8T。  
resourceManager,namenode 在同一节点上，且该节点不包括datanode和nodeManager服务。  
剩余28节点均包含了datanode和nodeManager服务  
最近集群做TB级数据随机化实验，hdfs各节点数据分布不太均衡，10台磁盘容量为1.8T的机器磁盘全部占满，导致这些节点上yarn的nodemanager 没有足够的空间，致使9个nodemanager 停止接受服务，1个nodemanager 服务终止，且无法启动。

考虑将10台低容量磁盘机器datanode角色停止授权，数据分发到其他大容量机器上，并删除hdfs数据。

在停止授权期间，我给集群又添加了一台32核，128G内存 1.8T磁盘的机器，分配了nodeManager角色。  
上述工作顺利完成后，重新启动yarn.

大部分机器正常工作，只有上述服务终止的nodemanager依然无法启动，查询日志报错如下：

Maybe a sst file got corrupt can you try to remove the folder of /var/log/hadoop-yarn/nodemanager/recovery-state from failed nodemanagers and check if starts?  
These files stays in the system even if you decomission the nodes.  
上述文件在节点上并不存在。故继续查看日志：

发现疑似目录：/var/lib/hadoop-yarn/yarn-nm-recovery/yarn-nm-state下存在：
    005615.sst  005638.log  005640.log  CURRENT  LOCK  MANIFEST-004397
    移除所有文件。重启nodemanager 成功。
    回顾错误原因可能是，我在该nodemanager终止情况下，在集群中添加了新的nodemanager，使得角色数目增加，而启动失败的nodemanager时，它使用存储的状态来恢复，在和数据库校验过程中发现数目不符合而启动失败。因此删除上述目录下的文件。
