I was using AWS HBase over EMR and then thrift server spinned over the
HBase server. while setting up the thrift server, there is an option in AWS
Management console to set the allowed IP addresses and the port numbers. I
was allowing the port number as 9000 , but the thrift server listens at
port number 9090. Once I added the port number 9090 to the allowed port
number list I was able to connect to it.
