如何从kafka_2.10-0.8.1.1中移除不一致的kafka主题元数据
如何从kafka_2.10-0.8.1.1中移除不一致的kafka主题元数据

想知道如何从zookeeper似乎具有主题(T_60036)元数据的独特情况中恢复，但broker没有相应的日志文件，导致生产者失败并出现异常
kafka.common.FailedToSendMessageException下面是我们注意到的：
在zookeeper中，/brokers/topics/T_60036和/config/topics/T_60036路径都存在。
kafka@kafka-3:~$ /opt/kafka/kafka_2.10-0.8.1.1/bin/zookeeper-shell.sh
localhost:2181 get /brokers/topics/T_60036/partitions/0/state
Connecting to localhost:2181
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
{"controller_epoch":6,"leader":1,"version":1,"leader_epoch":0,"isr":[1,2]}
cZxid = 0x80013308c
ctime = Wed Jun 06 04:55:37 UTC 2018
mZxid = 0x80013308c
mtime = Wed Jun 06 04:55:37 UTC 2018
pZxid = 0x80013308c
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 74
numChildren = 0
kafka@kafka-3:~$ /opt/kafka/kafka_2.10-0.8.1.1/bin/zookeeper-shell.sh
localhost:2181 get /config/topics/T_60036
Connecting to localhost:2181
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
{"version":1,"config":{}}
cZxid = 0x800132992
ctime = Wed Jun 06 04:55:13 UTC 2018
mZxid = 0x800132992
mtime = Wed Jun 06 04:55:13 UTC 2018
pZxid = 0x800132992
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 25
numChildren = 0但没有此主题的日志文件：
kafka@kafka-3:~$ ls -l /var/kafka/topics/T_60036*
ls: cannot access /var/kafka/topics/T_60036*: No such file or directory我确实读了主题删除here的第二条评论，但我担心它可能会破坏整个集群的稳定。我的问题是，在不重新启动或危害集群的情况下，从zookeeper中删除孤立的zookeeper条目("/config/topics/T_60036“、"/brokers/topics/T_60036")是否安全。
下面是我们的配置
Version: kafka_2.10-0.8.1.1
Cluster Configuration: 4 kafka brokers + 4 zookeeper
