Since we always load the native library this means we may use native libraries even if io.native.lib.available is set to false. > Let's make the flag to work as advertised - rather than always load the native hadoop library we only attempt to load the library (and report that native is available) if this flag is set. Since io.native.lib.available defaults to true the default behavior should remain unchanged (except that now we wont actually try to load the library if this flag is disabled). -- This message was sent by Atlassian JIRA (v6.2#6252)
