Subject JNI native-method warning in HDP 2.0
Date Thu, 16 Oct 2014 19:05:54 GMT
We are seeing a warning deep in HDFS code, I was wondering if anyone knows of this or if a
JIRA has been filed or fixed?  Searching on the warning text didn't crop up anything.  It
is not harmful AFAIK.

[Dynamic-linking native method java.net.NetworkInterface.init ... JNI]
WARNING in native method: JNI FindClass received a bad class descriptor "Ljava/net/InetAddress;".
 A correct class descriptor has
no leading "L" or trailing ";".  Incorrect descriptors will not be accepted in future releases.
