Haymant Mangla updated HIVE-24946:
----------------------------------
Description:
To handle:
# Introduce two states of failover db property to denote nature of database at
the time failover was initiated.
# If failover start config is enabled and dump directory contains failover
marker file, then in incremental load as a preAckTask, we should
## Remove repl.target.for from target db.
## Set repl.failover.endpoint = "TARGET"
## Updated the replication metrics saying that target cluster is failover ready
# In the first dump operation in reverse direction, presence of failover ready
marker and repl.failover.endpoint = "TARGET" will be used as indicator for
bootstrap iteration.
# In any dump operation except the first dump operation in reverse dxn, if
repl.failover.endpoint is set for db and failover start config is set to false,
then remove this property.
# In incremental load, if the failover start config is disabled, then add
repl.target.for and remove repl.failover.endpoint if present.
was:
* Update metric during load to capture the readiness for failover
* Remove repl.target.for property on target cluster
* Prepare the dump directory to be used during failover first dump operation
> Handle failover case during Repl Load
