[jira] [Commented] (PHOENIX-1359) Backward compatibility fails with
4.1 client and current 4.0 branch on server
[ https://issues.apache.org/jira/browse/PHOENIX-1359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14174372#comment-14174372 ]
James Taylor commented on PHOENIX-1359:
---------------------------------------
[~maryannxue] - I suspect you added more information that gets serialized for the join work you're doing? If so, make sure that if the cluster has 4.2 installed on it that it can still process queries sent from a 4.1 client. Usually that means detecting EOFException and having defaults for the extra values that were added.

> Query example: select * from LOYALTY_PROGRAM_CONDITION JOIN LOYALTY_PROGRAM on LOYALTY_PROGRAM_CONDITION__c.LOYALTY_PROGRAM_ID = LOYALTY_PROGRAM__c.ENTITY_ID where LOYALTY_PROGRAM__c.NAME='Ferrari' AND LOYALTY_PROGRAM_CONDITION.COUNTRY = 'Italy' limit 100;
