    Description

      Seeing an error from the SDK under this KV scenario, with pre-MH servers only

      Operations: Continuous upserts and gets 

      Change: Failover the entry point node.

      Cluster:

      1. kv <- removed, (used as the connection string)
      2. kv,index,fts,n1ql 
      3. kv,index,fts,n1ql
      4. kv,index,fts,n1ql

      Error: Seeing a couple errors but it settles on a repeated authentication error 

      2020-04-01 04:07:01.7551||Couchbase.Core.IO.Authentication.ScramShaMechanism|ERROR|Authentication failed. Cannot authenticate the user. Reason: AuthenticationError

      Full logs attached -> SdkdConsole.log.zip , and for the run logs http://sdkbuilds.sc.couchbase.com/view/.NET/job/sdk-net-situational-release/job/SDK3.0-Release/job/net-centos-alice/3/consoleFull (which has some more of the sdkd logs in context, specifically if you look after "Master node being removed from cluster. Switching", you'll see where the errors begin).

       

      Note: This issue causes 6 test failures, all of which involve removing the EPT node whilst running KV ops (upsert, get and subdoc). This is the most basic of the test scenarios where the EPT node is just ejected.

          Hi Will -

          I tried to recreate this and couldn't exactly on current master head. I am not sure if its fixed or I simply am not doing the right thing to trigger it. Let's meet next week to discuss.
