-----------------------------------
Summary: Translation of LocalResources via Tez plan serialization
can be lossy
Key: TEZ-2397
URL: https://issues.apache.org/jira/browse/TEZ-2397
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.4.0
Reporter: Siddharth Seth
Assignee: Siddharth Seth
Priority: Critical
Happens when there's no port information. The way we serialize a YarnURL into a
string causes the reconstructed path to include the port as -1, which is an
invalid URL. Path/URL reconstruction from this causes the hostname to be lost.
This is problematic on clusters running HDFA HA - since there's no host:port
information, only a service name. I'd imaging it'll be a problem for viewfs as
well.
