# 列出集群中的 master server

# 查看指定tserver_address的状态

修复replicas

sudo -u kudu kudu cluster ksck master1,master2,master3 > ./ksck.out 2>&1
发现有56个表处于非健康状态：
==================
Errors:
==================
table consistency check error: 56 out of 183 table(s) are not healthy
 
举例：
在ksck.out中可以看到具体是哪个表的哪个tablet出问题了：
The consensus matrix is:
 Config source |   Replicas   | Current term | Config index | Committed?
---------------+--------------+--------------+--------------+------------
 master        | A   B   C*   |              |              | Yes
 A             | A   B   C*   | 1427         | 2450         | Yes
 B             | A   B   C*   | 1427         | 2450         | Yes
 C             | A   B   C*   | 1427         | 2450         | Yes
Tablet 3689e076ed354f94a0967d1eed4b7d16 of table 'impala::dl_zz_kudu.tm_scada_hdzysj_change' is unavailable: 2 replica(s) not RUNNING
  868688d5077b4e02b14a8a0a57958668: TS unavailable
  0b4f24052ed74405b5d58fecd83f33e7: TS unavailable
  a59cf0d8d1ed45d8b1af094f4a28d686 (xxxxx:7050): RUNNING [LEADER]
 
0 replicas' active configs differ from the master's.
  All the peers reported by the master and tablet servers are:
  A = 0b4f24052ed74405b5d58fecd83f33e7
  B = 868688d5077b4e02b14a8a0a57958668
  C = a59cf0d8d1ed45d8b1af094f4a28d686
 
可以看到只有a59cf0d8d1ed45d8b1af094f4a28d686这一个replication是好的，另外俩都不可用了。
修复命令：
sudo -u kudu kudu remote_replica unsafe_change_config xxxx:7050 3689e076ed354f94a0967d1eed4b7d16 a59cf0d8d1ed45d8b1af094f4a28d686

sudo -u kudu kudu remote_replica unsafe_change_config xxxx:7050 {tablet_id} {replica_id}
