[jira] [Commented] (IGNITE-2895) OS info in console is incorrect when using x86 JRE on x64 Windows

["Alex (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-2895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15979639#comment-15979639 ] 

Alex commented on IGNITE-2895:
------------------------------

OS detection code uses System.getProperty("os.arch"); Please look at IgniteUtils.

64-bit Windows platforms always set architecture 32-bit to all 32-bit processes in WOW64 for compatibility reasons.
see MSDN: https://msdn.microsoft.com/en-us/library/aa384274(v=vs.85).aspx

can use code for detection: 
String arch = System.getenv("PROCESSOR_ARCHITECTURE");
String wow64Arch = System.getenv("PROCESSOR_ARCHITEW6432");
String realArch = arch.endsWith("64") || wow64Arch != null && wow64Arch.endsWith("64") ? "64" : "32";

Should we use os arch in log or platform (JVM) arch is sufficient?

for example Hadoop uses platform name in log:
see https://github.com/apache/hadoop/blob/f67237cbe7bc48a1b9088e990800b37529f1db2a/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/util/PlatformName.java#L35
and https://github.com/apache/hadoop/blob/f67237cbe7bc48a1b9088e990800b37529f1db2a/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/util/LightWeightGSet.java#L396

Spark uses Scala verison in log:
see: https://github.com/apache/spark/blob/17ce0b5b3f6a825fc77458bc8608cece1a6019c7/repl/scala-2.10/src/main/scala/org/apache/spark/repl/SparkILoopInit.scala#L33
