Add version to servers' startup massage.
----------------------------------------
Key: HADOOP-2586
URL: https://issues.apache.org/jira/browse/HADOOP-2586
Project: Hadoop
Issue Type: Improvement
Affects Versions: 0.15.0
Reporter: Konstantin Shvachko
It would be useful if hadoop servers printed hadoop version as a part of the
startup message:
{code}
/************************************************************
STARTUP_MSG: Starting NameNode
STARTUP_MSG: host = my-hadoop-host
STARTUP_MSG: args = [-upgrade]
STARTUP_MSG: Version = 0.15.1, r599161
************************************************************/
{code}
This would simplify understanding the logs.
