Aaron Davidson resolved SPARK-4805. ----------------------------------- Resolution: Fixed Assignee: Sean Owen > BlockTransferMessage.toByteArray() trips assertion > -------------------------------------------------- > > Key: SPARK-4805 > URL: https://issues.apache.org/jira/browse/SPARK-4805 > Project: Spark > Issue Type: Bug > Components: Shuffle > Affects Versions: 1.1.0 > Reporter: Sean Owen > Assignee: Sean Owen > > The {{ByteBuf}} below is allocated to have enough room to encode just the > message, but a type byte is written too. The buffer resizes and is left with > capacity, which is a minor waste. But when assertions are on, it fails the > assertion below. This is triggered by unit tests, but the Java test for this > wasn't running. You can verify that a simple "+1" in the allocated size fixes > it. > {code} > public byte[] toByteArray() { > ByteBuf buf = Unpooled.buffer(encodedLength()); > buf.writeByte(type().id); > encode(buf); > assert buf.writableBytes() == 0 : "Writable bytes remain: " + > buf.writableBytes(); > return buf.array(); > } > {code} > [~ilikerps] -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
