[jira] [Created] (KUDU-2948) ksck claims output is different but it’s actually the same
Abhishek created KUDU-2948:
------------------------------
Summary: ksck claims output is different but it’s actually the same
Key: KUDU-2948
URL: https://issues.apache.org/jira/browse/KUDU-2948
Project: Kudu
Issue Type: Bug
Components: ksck
Affects Versions: 1.7.0
Environment: RHEL 7.7
Reporter: Abhishek
I came across this scenario where ksck reports the tablet has mismatched consensus and configs disagree with the master's but they do not seem to be:
The consensus matrix is:
Config source | Replicas | Current term | Config index | Committed?
---------------+--------------+--------------+--------------+------------
master | A B* C | | | Yes
A | A B* C | 2939 | 20571 | Yes
B | A B* C | 2939 | 20571 | Yes
C | A B* C | 2939 | 20571 | Yes
Tablet 8137349615944d45a0897090d36d7a08 of table 'impala::<TableName>' is conflicted: Tablet 8137349615944d45a0897090d36d7a08 of table 'impala::<TableName>' replicas' active configs disagree with the master's

All the peers reported by the master and tablet servers are:
A = 6684505cec6f4a49b3442786cebdf06d
B = 8a3232953edd4ba79d20711d4ea3581d
C = c8b68cb1366c45199668247d4d7c0295
The consensus matrix is:
Config source | Replicas | Current term | Config index | Committed?
---------------+--------------+--------------+--------------+------------
master | A B* C | | | Yes
A | A B* C | 5030 | 6114195 | Yes
B | A B* C | 5030 | 6114195 | Yes
C | A B* C | 5030 | 6114195 | Yes
Table impala::<TableName> has 1 tablet(s) with mismatched consensus

0 replicas' active configs differ from the master's.
All the peers reported by the master and tablet servers are:
A = 1b6a44eadcd145f693390587c4e3308a
B = 36f1c8c3863a49778adeb6f40c73aa26
C = 6c8fc8452f374672abdae3098a198101
Tablet servers are under high load - noticed many backpressure messages and the drives for data_dirs and wal_dis are encrypted using navencrypt.
