Dongjoon Hyun updated SPARK-27275: ---------------------------------- Affects Version/s: 2.2.0 2.3.0 > Potential corruption in EncryptedMessage.transferTo > --------------------------------------------------- > > Key: SPARK-27275 > URL: https://issues.apache.org/jira/browse/SPARK-27275 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 2.2.0, 2.3.0, 2.4.0 > Reporter: Shixiong Zhu > Assignee: Shixiong Zhu > Priority: Major > Labels: correctness > Fix For: 2.3.4, 2.4.2, 3.0.0 > > > `EncryptedMessage.transferTo` has a potential corruption issue. When the > underlying buffer has more than `1024 * 32` bytes (this should be rare but it > could happen in error messages that send over the wire), it may just send a > partial message as `EncryptedMessage.count` becomes less than `transferred`. > This will cause the client hang forever (or timeout) as it will wait until > receiving expected length of bytes, or weird errors (such as corruption or > silent correctness issue) if the channel is reused by other messages. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
