Konstantin Shvachko updated HADOOP-6637:
----------------------------------------
Attachment: miniRPCBenchmark.patch
The patch includes MiniRPCBenchmark, the test, and the change to the script
file, which makes the benchmark runnable using
{code}
bin/hadoop org.apache.hadoop.ipc.MiniRPCBenchmark
{code}
An excerpt from JavaDoc:
{{MiniRPCBenchmark}} measures time to establish an RPC connection to a secure
RPC server. It sequentially establishes connections the specified number of
times, and calculates the average time taken to connect. The time to connect
includes the server side authentication time.
The benchmark supports three authentication methods:
# simple - no authentication. In order to enter this mode the configuration
file {{core-site.xml}} should specify {{hadoop.security.authentication =
simple}}. This is the default mode.
# kerberos - kerberos authentication. In order to enter this mode the
configuration file {{core-site.xml}} should specify
{{hadoop.security.authentication = kerberos}} and the argument string should
provide qualifying keytabFile and userName parameters.
# delegation token - authentication using delegation token. In order to enter
this mode the benchmark should provide all the mentioned parameters for
kerberos authentication plus the useToken argument option.
Input arguments:
* numIterations - number of connections to establish
* keytabFile - keytab file for kerberos authentication
* userName - principal name for kerberos authentication
* useToken - should be specified for delegation token authentication
* logLevel - logging level, see Level
