Teddy Choi created HIVE-26600: --------------------------------- Summary: Handle failover during optimized bootstrap Key: HIVE-26600 URL: https://issues.apache.org/jira/browse/HIVE-26600 Project: Hive Issue Type: Bug Reporter: Teddy Choi Assignee: Rakshith C
when the reverse policy is enabled from DR to PROD, there is a situation wherein the user may initiate a failover from DR to PROD before the optimized bootstrap is ever run. Current observations: * Repl Dump will place a failover ready marker but failover metadata won't be generated. * Repl Load will throw an error since failover will be set to true but failovermetadata is missing. Replication fails and we reach an undefined state. Fix : * create failover ready marker only during second cycle of optimized bootstrap if possible. * since some tables may need to be bootstrapped, it may take upto 3 cycles before failover from DR to PROD is complete. * if no tables are modified, second dump from DR to PROD will be marked as failover ready. Result: * users can initiate a failover immediately after enabling reverse policy without any hassles. -- This message was sent by Atlassian Jira (v8.20.10#820010)
