Class HardcodedStackVersionPropertiesCheck

java.lang.Object

org.apache.ambari.server.checks.ClusterCheck

org.apache.ambari.server.checks.HardcodedStackVersionPropertiesCheck

All Implemented Interfaces:

org.apache.ambari.spi.upgrade.UpgradeCheck

public class HardcodedStackVersionPropertiesCheck
extends ClusterCheck

Checks for properties that contain hardcoded CURRENT hdp version string. Presence of such properties usually means that some paths are hardcoded to point to concrete version of HDP, instead of pointing to current symlink. That is a potential problem when doing stack update.
