There are two advantages to use `MemoryBlock`.\r\n\r\n1. Has clean API calls rather than using a Java array or `PlatformMemory`\r\n2. Improve runtime performance of memory access instead of using `Object` with `Platform.get/put...`.\r\n\r\n## How was this patch tested?\r\n\r\nUsed existing UTs"},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/380326099","html_url":"https://github.com/apache/spark/pull/20874#issuecomment-380326099","issue_url":"https://api.github.com/repos/apache/spark/issues/20874","id":380326099,"user":{"login":"AmplabJenkins","id":4031291,"avatar_url":"https://avatars3.githubusercontent.com/u/4031291?v=4","gravatar_id":"","url":"https://api.github.com/users/AmplabJenkins","html_url":"https://github.com/AmplabJenkins","followers_url":"https://api.github.com/users/AmplabJenkins/followers","following_url":"https://api.github.com/users/AmplabJenkins/following{/other_user}","gists_url":"https://api.github.com/users/AmplabJenkins/gists{/gist_id}","starred_url":"https://api.github.com/users/AmplabJenkins/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AmplabJenkins/subscriptions","organizations_url":"https://api.github.com/users/AmplabJenkins/orgs","repos_url":"https://api.github.com/users/AmplabJenkins/repos","events_url":"https://api.github.com/users/AmplabJenkins/events{/privacy}","received_events_url":"https://api.github.com/users/AmplabJenkins/received_events","type":"User","site_admin":false},"created_at":"2018-04-11T04:48:36Z","updated_at":"2018-04-11T04:48:36Z","author_association":"NONE","body":"Merged build finished.
