----------------------------------------
Summary: exception.c compile macro fights the future
Key: HADOOP-19756
URL: https://issues.apache.org/jira/browse/HADOOP-19756
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.4.2
Reporter: Edward Capriolo
The macro in exception.c is backwards
{code:java}
// MT-Safe under Solaris or glibc >= 2.32 not supporting sys_errlist/sys_nerr
#if defined(__sun)
#define USE_STR_ERROR
#elif defined(__GLIBC_PREREQ)
#if __GLIBC_PREREQ(2, 32)
#define USE_STR_ERROR
#endif
#endif {code}
If penalizes those implementing the standard like alpine musc. If the logic is
reversed platforms meeting the standard work out of the box.
