Refactored the code so the model is compressed based on the storage. We may try compression based on the prediction time. \r\n\r\nAlso, I found that diffSum will be always zero mathematically, so no corrections are required."},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/97608349","html_url":"https://github.com/apache/spark/pull/5767#issuecomment-97608349","issue_url":"https://api.github.com/repos/apache/spark/issues/5767","id":97608349,"user":{"login":"SparkQA","id":8108735,"avatar_url":"https://avatars.githubusercontent.com/u/8108735?v=3","gravatar_id":"","url":"https://api.github.com/users/SparkQA","html_url":"https://github.com/SparkQA","followers_url":"https://api.github.com/users/SparkQA/followers","following_url":"https://api.github.com/users/SparkQA/following{/other_user}","gists_url":"https://api.github.com/users/SparkQA/gists{/gist_id}","starred_url":"https://api.github.com/users/SparkQA/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/SparkQA/subscriptions","organizations_url":"https://api.github.com/users/SparkQA/orgs","repos_url":"https://api.github.com/users/SparkQA/repos","events_url":"https://api.github.com/users/SparkQA/events{/privacy}","received_events_url":"https://api.github.com/users/SparkQA/received_events","type":"User","site_admin":false},"created_at":"2015-04-29T22:46:54Z","updated_at":"2015-04-29T22:46:54Z","body":"  [Test build #31329 has finished](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/31329/consoleFull) for   PR 5767 at commit [`5e346c9`](https://github.com/apache/spark/commit/5e346c9cd61e729a9bbe015bff886ff45ab3654a).\n * This patch **passes all tests**.\n * This patch merges cleanly.\n * This patch adds no public classes.\n * This patch does not change any dependencies."}}
