ATTACHMENT ID: 12932119 - PreCommit-HIVE-Build > Arrow SerDe leaks a DirectByteBuffer > ------------------------------------ > > Key: HIVE-20203 > URL: https://issues.apache.org/jira/browse/HIVE-20203 > Project: Hive > Issue Type: Bug > Reporter: Eric Wohlstadter > Assignee: Eric Wohlstadter > Priority: Blocker > Attachments: HIVE-20203.1.patch > > > ArrowColumnarBatchSerDe allocates an arrow NullableMapVector for each task > that uses the serde. > The vector is a DirectByteBuffer allocated from Arrow's off-heap buffer pool. > This buffer is never closed and leaks about 1K of physical memory for each > task. > This patch does three things: > # Ensure the buffer is closed when the RecordWriter for the task is closed. > # Adds per-task memory accounting by assigning a ChildAllocator to each task > from the RootAllocator. > # Enforces that the ChildAllocator for a task has released all memory > assigned to it, when the task is completed. > The patch assumes that close() is always called on the RecordWriter when a > task is finished (even if there is a failure during task execution). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
