You are allocating 8-bytes by calling this constructor. Without a growing the buffer, you allocate a byte array of 8 bytes to the ```UnsafeRow```, which is happening here. You would need at least 16 bytes for ```UnsafeRow``` to work (8 for the bitset and 8 for the long).\r\n\r\n```BufferHolder``` is meant to be used with ```Unsafe*Writer``` classes. I don't think it adds much value here. I think we should just use a 16 byte array instead.","created_at":"2015-12-17T19:52:43Z","updated_at":"2015-12-17T19:52:43Z","html_url":"https://github.com/apache/spark/pull/10335#discussion_r47952489","pull_request_url":"https://api.github.com/repos/apache/spark/pulls/10335","_links":{"self":{"href":"https://api.github.com/repos/apache/spark/pulls/comments/47952489"},"html":{"href":"https://github.com/apache/spark/pull/10335#discussion_r47952489"},"pull_request":{"href":"https://api.github.com/repos/apache/spark/pulls/10335"}}},"pull_request":{"url":"https://api.github.com/repos/apache/spark/pulls/10335","id":53890636,"html_url":"https://github.com/apache/spark/pull/10335","diff_url":"https://github.com/apache/spark/pull/10335.diff","patch_url":"https://github.com/apache/spark/pull/10335.patch","issue_url":"https://api.github.com/repos/apache/spark/issues/10335","number":10335,"state":"open","locked":false,"title":"[Spark-12374][SPARK-12150][SQL] Adding logical/physical operators for Range","user":{"login":"gatorsmile","id":11567269,"avatar_url":"https://avatars.githubusercontent.com/u/11567269?v=3","gravatar_id":"","url":"https://api.github.com/users/gatorsmile","html_url":"https://github.com/gatorsmile","followers_url":"https://api.github.com/users/gatorsmile/followers","following_url":"https://api.github.com/users/gatorsmile/following{/other_user}","gists_url":"https://api.github.com/users/gatorsmile/gists{/gist_id}","starred_url":"https://api.github.com/users/gatorsmile/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gatorsmile/subscriptions","organizations_url":"https://api.github.com/users/gatorsmile/orgs","repos_url":"https://api.github.com/users/gatorsmile/repos","events_url":"https://api.github.com/users/gatorsmile/events{/privacy}","received_events_url":"https://api.github.com/users/gatorsmile/received_events","type":"User","site_admin":false},"body":"Based on the suggestions from @marmbrus , added logical/physical operators for Range for improving the performance. \r\n\r\nAlso added another API for resolving the JIRA Spark-12150. \r\n\r\nCould you take a look at my implementation, @marmbrus ?
