Yingjie Cao created FLINK-21951: ----------------------------------- Summary: Fix wrong if condition in BufferReaderWriterUtil#writeBuffers Key: FLINK-21951 URL: https://issues.apache.org/jira/browse/FLINK-21951 Project: Flink Issue Type: Sub-task Components: Runtime / Network Reporter: Yingjie Cao Fix For: 1.13.0
The wrong if condition in BufferReaderWriterUtil#writeBuffers may lead to data loss when bulk writing a large amount of data into file. This is a bug intruded since 1.9, but only small amount of data is written, so the bug never occurs. In 1.13, the sort-merge shuffle uses it to write more data which triggers the bug. -- This message was sent by Atlassian Jira (v8.3.4#803005)
