Arup Malakar commented on HIVE-4911:
------------------------------------
I thought I will add the performance numbers I have seen here for reference.
In my testing I have observed that with auth-conf the amount of time taken
to transfer data is {color:red}~2.3 times{color} the time it takes without
encryption. In my test I have a table of size *1GB*, and I did
"select *" on the table using the jdbc driver once with encryption and once
without encryption.
Time taken:
* No encryption: *~9 minutes*
* Encryption: *~20 minutes*
I was wondering if anyone has experience with SASL encryption, if it is
possible to tune any JVM/SASL settings to bring down this time. I am also
interested in understanding if it is advisable to use a different crypto
provider than the default one that ships with the JDK. If this much overhead is
to be expected with encryption methods I would like to know that too. I am
using patched version of _hive-10_ with _Hive Server 2_ on _hadoop 23/jdk
1.7/RHEL 5_.
PS: This comment is a repost of a mail I sent out to hive-dev mailing list.

> The QoP for hive server 2 should be configurable to enable encryption. A new
> configuration should be exposed "hive.server2.thrift.rpc.protection". This
> would give greater control configuring hive server 2 service.
