ambari-web/app/data/HDP2/site_properties.js <https://reviews.apache.org/r/28197/#comment104023> This property and below property are having *isRequired* attribute set to false. ambari-web code sets this flag to false for the properties for which it is ok to have *no value* (otherwise web code gives validation error for *no value* properties) Is this intentional ? NOTE: If *isRequired* attribute is not mentioned then it defaults to true - Jaimin Jetly On Nov. 19, 2014, 12:53 a.m., Alejandro Fernandez wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
