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 http://mail-archives.apache.org/mod_mbox/incubator-cassandra-user/201409.mbox/%3CCALHCZd7RGSahJUbK32WoTr9JRoA+4K=mrfocmxuk0nbzoqq...@mail.gmail.com%3E 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.
