Vishal Ranjan created SAMZA-2681:
------------------------------------
Summary: Malformed URL exception while deploying Samza on a pure
IPv6 VM
Key: SAMZA-2681
URL: https://issues.apache.org/jira/browse/SAMZA-2681
Project: Samza
Issue Type: Bug
Environment: Pure IPv6 deployment
Reporter: Vishal Ranjan
In our product we are expanding our support for IPv6 environment.
We earlier tested deploying Samza in a dual stack environment, and it worked
fine.
Recently we got our hands on a pure IPv6 lab, and while testing we came across
an issue when starting Samza.
Looking at the stack trace it seems like the url is not formed correctly for
IPv6 deployment. The IPv6 address should have been decorated inside '[ ]’, but
that isn’t the case.
Here is the stack trace. The ip of the VM where Samza is deployed is
'fc00:192:168:22::14’.
