Nate Edel updated HDFS-8078:
----------------------------
Description:
1st exception, on put:
15/03/23 18:43:18 WARN hdfs.DFSClient: DataStreamer Exception
java.lang.IllegalArgumentException: Does not contain a valid host:port
authority: 2401:db00:1010:70ba:face:0:8:0:50010
at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:212)

org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:588)
Appears to actually stem from code in DataNodeID which assumes it's safe to
append together (ipaddr + ":" + port) -- which is OK for IPv4 and not OK for
IPv6. NetUtils.createSocketAddr( ) assembles a Java URI object, which requires
the format proto://[2401:db00:1010:70ba:face:0:8:0]:50010
Currently using InetAddress.getByName() to validate IPv6 (guava
InetAddresses.forString has been flaky) but could also use our own parsing.
(From logging this, it seems like a low-enough frequency call that the extra
object creation shouldn't be problematic, and for me the slight risk of passing
in bad input that is not actually an IPv4 or IPv6 address and thus calling an
external DNS lookup is outweighed by getting the address normalized and
avoiding rewriting parsing.)
Alternatively, sun.net.util.IPAddressUtil.isIPv6LiteralAddress()

Which also comes as client error "-get: 2401 is not an IP string literal."
This one has existing parsing logic which needs to shift to the last colon
rather than the first. Should also be a tiny bit faster by using lastIndexOf
rather than split. Could alternatively use the techniques above.
