I just documented this in the wiki on both pages [~leftylev] mentioned.

> The http connection parameters are currently part of the HiveConf section of the connection
string. It should ideally be part of SessionConf section, as that is where rest of the connection
parameters are.
> HTTP transport parameters are not part of the hiveconfiguration parameters that need
to be set.
> ie
> instead of 
> jdbc:hive2://<host>:<port>/<db>?hive.server2.transport.mode=http;hive.server2.thrift.http.path=<http_endpoint>
> it should be -
> jdbc:hive2://<host>:<port>/<db>;transportMode=http;httpPath=<http_endpoint>
> *Release Note:*
> The JDBC Uri for HiveServer2 has the form:
> {code}
> jdbc:hive2://host1:port1,host2:port2/dbName;sess_var_list?hive_conf_list#hive_var_list
> {code}
> Ideally, sess_var_list is supposed to be used to pass parameters that will be used within
the JDBC Driver. However, some of the http mode parameters were being passed in the hive_conf_list
which we've fixed now (in a backward compatible way).
> Additionally, JDBC Driver has a naming convention for the parameters in the JDBC Uri
which were not followed to the sasl.qop parameter. We've renamed it in a backward compatible
way.
> Details:
> *1. HTTP Mode params:*
> *Old example uri:*
> {code}
> jdbc:hive2://host:port/dbName;user=username;password=password?hive.server2.transport.mode=http;hive.server2.thrift.http.path=httpEndpoint
> {code}
> *New example uri:*
> {code}
> jdbc:hive2://host:port/dbName;user=username;password=password;transportMode=http;httpPath=httpEndpoint?hive.server2.logging.operation.enabled=false
> {code}
> As you can see above, {{hive.server2.transport.mode}} has been renamed to {{transportMode}},
{{hive.server2.thrift.http.path}} has been renamed to {{httpPath}} and both have been moved
from {{hive_conf_list}} to {{sess_var_list}}.
> *2. Sasl qop renaming:*
> *Old example uri:*
> {code}
> jdbc:hive2://host:port/dbName;principal=hiveserver2KerberosPrincipal;sasl.qop=qopValue
> {code}
> *New example uri:*
> {code}
> jdbc:hive2://host:port/dbName;principal=hiveserver2KerberosPrincipal;saslQop=qopValue
> {code}
> As you can see {{sasl.qop}} has been renamed to {{saslQop}}.
> Note: all changes are backward compatible and print a deprecation message like the following:
> {code}
> 0: jdbc:hive2://localhost:10001> !connect jdbc:hive2://localhost:10001/;sasl.qop=auth?hive.server2.transport.mode=http;hive.server2.thrift.http.path=cliservice
