--------------------------------------------------------

             Summary: hs2 jdbc url - wrong connection string cause OOM error on beeline/jdbc/odbc
client, misleading message
                 Key: HIVE-10753
                 URL: https://issues.apache.org/jira/browse/HIVE-10753
             Project: Hive
          Issue Type: Bug

beeline -u 'jdbc:hive2://localhost:10001/default?httpPath=/;transportMode=http' -n hdiuser

Java heap space
Beeline version 0.14.0.2.2.4.1-1 by Apache Hive
0: jdbc:hive2://localhost:10001/default (closed)> ^Chdiuser@headnode0:~$ 

But it works if I use the deprecated param - 

hdiuser@headnode0:~$ beeline -u 'jdbc:hive2://localhost:10001/default?hive.server2.transport.mode=http;httpPath=/'
-n hdiuser
scan complete in 12ms

The reason for the above message is :
The url is wrong. Correct one:
{code}
beeline -u 'jdbc:hive2://localhost:10001/default;httpPath=/;transportMode=http' -n hdiuser
{code}
Note the ";" instead of "?". The deprecation msg prints the format as well: 
{code}
Please use transportMode like so: jdbc:hive2://<host>:<port>/dbName;transportMode=<transport_mode_value>
{code}
