Gargi Jaiswal updated HDDS-13075:
---------------------------------
    Description: 
{quote} * If not set, 
org.apache.hadoop.hdds.scm.container.placement.algorithms.SCMContainerPlacementRandom
 will be used as default value.{quote}
The default is actually SCMContainerPlacementRackAware (HDDS-8300)

Similarly the description text needs update for 
ozone.scm.container.placement.ec.impl.
