DSE install interfering with apache Cassandra 2.1.0

Hi All,

Just come across this one, I’m at a bit of a loss on how to fix it.

A user here did the following steps

On a MAC
Install Datastax Enterprise (DSE) using the dmg file
test he can connect using the DSE cqlsh window
Unistall DSE (full uninstall which stops the services)

download apache cassandra 2.1.0
unzip
change to the non directory run sudo ./cassandra

Now when he tries to connect using cqlsh from apache cassandra 2.1.0 bin   he gets

Connection error: ('Unable to connect to any servers', {'127.0.0.1': ConnectionShutdown('Connection <AsyncoreConnection(4528514448) 127.0.0.1:9160 (closed)> is already closed',)})

This is probably related to

but I can’t see why the uninstall of DSE is leaving the apache cassandra release cqlsh unable to attach to the apache cassandra runtime.

Without the apache cassandra running I ran jps -l on this machine ,the only result was

338 sun.tool.jps.Jps

The Mac didn’t like the netstat command so I ran

netstat -atp tcp |  grep 9160

no result

Also  for the native port:

netstat-atp tcp | grep 9042

gave no result (command may be wrong)

So I ran port scan using the network utility (between 0 and 10000).  Results as shown:


Port Scan has started…

Port Scanning host: 127.0.0.1

     Open TCP Port:     631            ipp
Port Scan has completed…


Hope this helps.

Please run jps to check which Java services are still running and to make sure if c* is running. Then please check if 9160 port is in use. netstat -nltp | grep 9160

This will confirm what is happening in your case.
