dns - Avro tool fails to convert from json due to IPv6 -


i trying convert simple json file avro using avro tools (1.7.7).

the command i've been running

java -jar ~/downloads/avro-tools-1.7.7.jar fromjson  --schema-file src/main/avro/twitter.avsc tweet.json > tweet.avro

on schema

{ "type": "record", "name": "tweet", "namespace": "co.feeb.avro", "fields": [     {         "name": "username",         "type": "string",         "doc": "screen name of user on twitter.com"     },     {         "name": "text",         "type": "string",         "doc": "the content of user's message"     },     {         "name": "timestamp",         "type": "long",         "doc": "unix epoch time in seconds"     } ], "doc": "schema twitter messages" }

i see exception after running command:

trying prefer ipv4 on ipv6 using -djava.net.preferipv4stack=true didn't help. (i running mac osx 10.10.3 , java 1.8.0_25-b17).

oh snap ... i've solved myself right after posting this. local router added ipv6 nameserver local machine.

changing assigned nameserver manually google's 8.8.8.8 fixed issue.
