Each time this function actually > download the whole app package from HDFS. If the app package is big, this is > rather inefficient. > The 3 places are: > 1) SliderClient.actionBuild() -> > AgentClientProvider.validateInstanceDefinition() > 2) AgentClientProvider.getApplicagionTags() > 3) AgentClientProvider.validateInstanceDefinition() > We should cache the metainfo object in AgentClientProvider. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
