Joe Pallas created HDFS-10189:
---------------------------------
Summary: PacketResponder toString is built incorrectly
Key: HDFS-10189
URL: https://issues.apache.org/jira/browse/HDFS-10189
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 2.7.1
Reporter: Joe Pallas
Priority: Minor
The constructor for {{BlockReceiver.PacketResponder}} says
{code}
final StringBuilder b = new StringBuilder(getClass().getSimpleName())
.append(": ").append(block).append(", type=").append(type);
if (type != PacketResponderType.HAS_DOWNSTREAM_IN_PIPELINE) {
b.append(", downstreams=").append(downstreams.length)
.append(":").append(Arrays.asList(downstreams));
}
{code}
So it includes the list of downstreams only when it has no downstreams. The
{{if}} test should be for equality.
