Is the server listening on port 3000?
Which server version are you using?
What type of data in located in namespace “test”/ set “zu”?
Can you send server configuration in “aerospike.conf”?
Is the client on the same operating system instance as the server?
yes

yes

Try the following command in aql:
aql> select * from test.zu
This command will result in a scan from the C client. I assume this fails as well?
Are you using the server in a Docker container?
Another command you can use to help you troubleshoot is to do “show scans”, which will give the state of the scan done by the database, weather done through java or aql.
Do any java client examples in the demo application work?
Yes all the others except for these scans
guidance please
I am still stuck at
The control doesnt come out of
while (pos < length) {
int count = bis.read(dataBuffer, pos, length - pos);
!!!
It’s not clear what is really happening in your case. There is some sort of networking issue going on. I suggest adding logging statements in the client code to obtain more information about cause of failure and run packaged scan example.
For example:
MultiCommand.java: in readBytes() add
Log.info("readBytes " + length);
Connection.java: right before socket.connect() add
Log.info("Connect " + address);
Node.java: in getConnection() change first block to following:
Log.info("getConnection " + timeoutMillis);
while ((conn = connectionQueue.poll()) != null) {
if (conn.isValid()) {
try {
conn.setTimeout(timeoutMillis);
Log.info("found connection " + conn);
return conn;
}
catch (Exception e) {
// Set timeout failed. Something is probably wrong with timeout
// value itself, so don't empty queue retrying. Just get out.
Log.info("connection failed " + conn);
closeConnection(conn);
throw new AerospikeException.Connection(e);
}
}
Log.info("connection not valid " + conn);
closeConnection(conn);
}
Log.info("create connection");
