I have 3 node cluster and install haproxy on node1.
the list of hive services running on my node 1 are : Metastore server, Webcat server, and HiveServer2.
one instance of hive server2 is running on node 2 and its working fine.
But node1 hive server2 is not running and showing this errot:
Error starting HiveServer2: could not start ThriftBinaryCLIService
org.apache.thrift.transport.TTransportException: Could not create ServerSocket on address 0.0.0.0/0.0.0.0:10000.

on cli its showing haproxy is using the port 10000
[root@cm1 singhkabir880]# netstat -tulpn | grep 10000tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 882/haproxy [root@cm1 singhkabir880]#
i have add hive server2 role first then install haproxy service and made below changes in :
/etc/haproxy/haproxy.cfg
:
listen hiveserver2 :10000
#haproxy will listen in port 10000 for hiveserver2 client requests.
mode tcp
option tcplog
balance leastconn
#tcp – connection mode between haproxy to hive servers
#leastconn – requests will be sent to server with less connection
server server1 node1:10000
server server2 node2:10000
What should do i need to order to start newly added hive server2 ?
Kindly Suggest.
