Description

This Jira is filed on behalf of Sudarshan Sharma:

1) Please refer following documentation at
http://impala.apache.org/docs/build/html/topics/impala_proxy.html#tut_proxy .

2) Example configuration has following.

listen impala :25003
mode tcp
option tcplog
balance leastconn

server symbolic_name_1 impala-host-1.example.com:21000
server symbolic_name_2 impala-host-2.example.com:21000
server symbolic_name_3 impala-host-3.example.com:21000
server symbolic_name_4 impala-host-4.example.com:21000

**********************
Request :-

**********************

There should be a "check" keyword at the end of each line that begins with "server". Can we please add? (most users are likely to copy - paste and replication and hence it would be best to keep it correct)

This is correct for the following pool mentioned later in the configuration.

---

listen impalajdbc :21051
mode tcp
option tcplog
balance source
server symbolic_name_5 impala-host-1.example.com:21050 check
server symbolic_name_6 impala-host-2.example.com:21050 check
server symbolic_name_7 impala-host-3.example.com:21050 check
server symbolic_name_8 impala-host-4.example.com:21050 check
