Tristan Tarrant <ttarrant> made a comment on jira ISPN-3376

Can you please include source and target logs ?

Vitalii Chepeliuk <vchepeli> made a comment on jira ISPN-3376

Added server logs

Testes and looks like this bug is not fixed. The same error as before
I do this  
    In order to perform a rolling upgrade of a HotRod cluster, the following steps must be taken 
    1. Configure and start a new cluster with a RemoteCacheStore pointing to the old cluster and the 
        hotRodWrapping flag enabled 
    2. Configure all clients so that they will connect to the new cluster 
        3. Invoke the 
        upgrade --dumpkeys command on the old cluster for all of the caches that need to be migrated 
    4. Invoke the 
        upgrade --synchronize=hotrod command on the new cluster to ensure that all data is migrated from the old cluster to the new one 
    5. Invoke the 
        upgrade --disconnectsource=hotrod command on the new cluster to disable the RemoteCacheStore used to migrate the data 
    6. Switch off the old cluster 
And get exception
And exception
ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server

Vitalii: I have tried several times and cannot reproduce this issue.

Here what I was doing, 
6.1.0.GA server
[remoting://localhost:9999/local/default]> upgrade --dumpkeys default
ISPN019502: Dumped keys for cache default

[remoting://localhost:9999/local/default]> upgrade --dumpkeys --all
ISPN019502: Dumped keys for cache default
ISPN019502: Dumped keys for cache namedCache
ISPN019502: Dumped keys for cache memcachedCache
ISPN019502: Dumped keys for cache ___defaultcache

[remoting://localhost:9999/local/default]> 
6.2.0.ER4 server
[remoting://localhost:10110/local/]> upgrade --synchronize=hotrod default
ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server
[remoting://localhost:10110/local/]>  upgrade --synchronize=hotrod 
ISPN019016: No such cache: 'null'
[remoting://localhost:10110/local/]> upgrade --synchronize=hotrod default
ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server
[remoting://localhost:10110/local/]> 
[remoting://localhost:10110/local/default]> upgrade --synchronize=hotrod --all
ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server


Maybe I am losing something but I do what is written what "help upgrade" says
in USAGE

ah, it looks like it's confusing the cache name with the synchronizer name

Yes, that's only problem remains I think

CR1 client uses new protocol version of hotrod 13. When 1.3 client communicates with 6.1.0 GA server following exception is thrown

Threre is no option for upgrade command to specify protocol version of hotrod client to be used.

Works nicely in CR2. Verified. 

The incorrect warning "ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server" (incorrect just because the migrator and the cache name are swapped in it) might still happen but only if there's another problem, such as configuration issue. 

The rolling upgrade process is smooth when performed correctly.

So I think this command does not work now properly
Steps to reproduce
1) Unzip ER4 build and copy to server0 folder
2) Unzip ER4 build and copy to server1 folder
3) copy sample configuration from examples/configs folder 
   a)cp server1/docs/examples/configs/standalone-hotrod-rolling-upgrade.xml to server1/standalone/configuration/
   b)cp server1/docs/examples/configs/standalone-rest-rolling-upgrade.xml to server1/standalone/configuration/
4) change configuration for server1/stanalone/configuration/standalone-hotrod-rolling-upgrade.xml
  a) change default port-offset from 0 to 100
  b) change remote-host to localhost in outbound socket binding configuration
5) start servers
  a) start server0, server0/bin/standalone.sh -c standalone.xml
  b) start server1, server1/bin/standalone.sh -c standalone-hotrod-rolling-upgrade.xml
6) connect to server via cli
  a) server0/bin/ispn-cli.ch
     connect localhost:9999
     cache default
     put --codec=hotrod key1 val1
     put --codec=hotrod key2 val2
     put --codec=hotrod key3 val3
     upgrade --dumpkeys --all
  Should see message
   ISPN019502: Dumped keys for cache namedCache
   ISPN019502: Dumped keys for cache default
   ISPN019502: Dumped keys for cache memcachedCache
   ISPN019502: Dumped keys for cache ___defaultcache
  b) server1/bin/ispn-cli.sh
     connect localhost:10099
     upgrade --synchronize=hotrod
  Following message is shown
    ISPN019026: An error occurred while synchronizing data for cache 'hotrod' using migrator 'default' from the source server

Here is output from my console
[standalone@localhost:10099 /] upgrade --synchronize=hotrod
