Compared to gapply() + collect(), gapplyCollect() offers performance optimization as well as programming convenience, as no schema is needed to be provided.\r\n\r\nThis is similar to dapplyCollect().\r\n\r\n## How was this patch tested?\r\nAdded test cases for gapplyCollect similar to dapplyCollect\r\n"},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/227591344","html_url":"https://github.com/apache/spark/pull/13760#issuecomment-227591344","issue_url":"https://api.github.com/repos/apache/spark/issues/13760","id":227591344,"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":"2016-06-21T22:27:36Z","updated_at":"2016-06-21T22:27:36Z","body":"**[Test build #60971 has started](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/60971/consoleFull)** for PR 13760 at commit [`1d62c38`](https://github.com/apache/spark/commit/1d62c38602e393a2e0707caec287aa3353f02b04)."}}
