Description

During a cross-stack upgrade, the PreChecks need to be able to run.

STR:

• Install BigInsights 4.2.5
• Upgrade Ambari to 2.5
• Register bits for HDP 2.6
• Install bits for HDP 2.6
• Attempt to run PreChecks

curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET http://localhost:8080/api/v1/clusters/c1/rolling_upgrades_check?fields=*&UpgradeChecks/repository_version=2.6.1.0-129&UpgradeChecks/upgrade_type=NON_ROLLING&UpgradeChecks/upgrade_pack=nonrolling-upgrade-to-hdp-2.6

This returns,

{
  "status" : 500,
  "message" : "org.apache.ambari.server.controller.spi.SystemException: Repository version null was not found"
}

because in UpgradeHelper.java it cannot find the upgrade pack.

The new API will requiring passing in a new argument, e.g., UpgradeChecks/target_stack=HDP-2.6
