---------------------------------------
Summary: Server.java swallows the reason why binding failed
Key: CASSANDRA-14544
URL: https://issues.apache.org/jira/browse/CASSANDRA-14544
Project: Cassandra
Issue Type: Bug
Reporter: James Roper
On line 164 of {{org/apache/cassandra/transport/Server.java}}, the cause of a
failure to bind to the server port is swallowed:
[https://github.com/apache/cassandra/blob/06209037ea56b5a2a49615a99f1542d6ea1b2947/src/java/org/apache/cassandra/transport/Server.java#L163-L164]
{code:java}
if (!bindFuture.awaitUninterruptibly().isSuccess())
throw new IllegalStateException(String.format("Failed to bind port
%d on %s.", socket.getPort(), socket.getAddress().getHostAddress()));
{code}
So we're told that the bind failed, but we're left guessing as to why. The
cause of the bind failure should be passed to the {{IllegalStateException}}, so
that we can then proceed with debugging, like so:
{code:java}
if (!bindFuture.awaitUninterruptibly().isSuccess())
throw new IllegalStateException(String.format("Failed to bind port
%d on %s.", socket.getPort(), socket.getAddress().getHostAddress()),
bindFuture.cause());
{code}
