Vinayakumar B commented on HADOOP-7824: --------------------------------------- After this, I started facing compile errors in NativeIO.c in windows, similar to below, {noformat} src\org\apache\hadoop\io\nativeio\NativeIO.c(145): error C2065: 'O_RDONLY' : undeclared identifier [C:\work\hadoop\mai n\hadoop-common-project\hadoop-common\src\main\native\native.vcxproj]{noformat} I am not JNI expert, but seeing the code change I understood that, from JNI trying to set the value of the constant in the Java class. And this constant name must be passed to {{SET_INT_OR_RETURN}}. So enclosing all these constants names in quotes solved the compilation error for me. Just followed similar to {{setStaticBoolean(env, clazz, "fadvisePossible", JNI_TRUE);}} Please someone with JNI expertise confirm whether this changes are correct? If so, I will raise a Jira and provide the patch to fix the compilation. > NativeIO.java flags and identifiers must be set correctly for each platform, > not hardcoded to their Linux values > ---------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-7824 > URL: https://issues.apache.org/jira/browse/HADOOP-7824 > Project: Hadoop Common > Issue Type: Sub-task > Components: native > Affects Versions: 0.20.204.0, 0.20.205.0, 1.0.3, 0.23.0, 2.0.0-alpha, 3.0.0 > Environment: Mac OS X, Linux, Solaris, Windows, ... > Reporter: Dmytro Shteflyuk > Assignee: Martin Walsh > Labels: hadoop > Fix For: 2.8.0 > > Attachments: HADOOP-7824.001.patch, HADOOP-7824.002.patch, > HADOOP-7824.003.patch, HADOOP-7824.004.patch, HADOOP-7824.patch, > HADOOP-7824.patch, hadoop-7824.txt > > > NativeIO.java flags and identifiers must be set correctly for each platform, > not hardcoded to their Linux values.
