Steve Loughran commented on SLIDER-1079: ---------------------------------------- Just catching up with my own review, missed it was already in. ( https://reviews.apache.org/r/43951/ ) . I think we should be preserving any reason for the metainfo load to fail and then rethrow it when needed, that way things don't get lost > Cache MetaInfo for AgentClientProvider > -------------------------------------- > > Key: SLIDER-1079 > URL: https://issues.apache.org/jira/browse/SLIDER-1079 > Project: Slider > Issue Type: Bug > Components: client > Affects Versions: Slider 0.81, Slider 0.90.2 > Reporter: shanyu zhao > Assignee: shanyu zhao > Attachments: SLIDER-1079.1.patch, SLIDER-1079.patch > > > During app creation, the slider client calls > AgentUtils.getApplicationMetainfo() 3 times. 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)
