---------------------------------------
Summary: YamlTreeReader does not support Yaml aliases
Key: NIFI-12404
URL: https://issues.apache.org/jira/browse/NIFI-12404
Project: Apache NiFi
Issue Type: Bug
Reporter: Daniel Stieglitz
Assignee: Daniel Stieglitz
Utilizing the Jackson library to parse YAML allowed for reuse of much of the
code used by the JsonTreeReader. A side effect though is Jackson does not
support the use of Yaml anchors and aliases. An example would be the following
Yaml
{code:java}
bill-to: &id001
street: |
123 Tornado Alley
Suite 16
city: East Centerville
state: KS
ship-to: *id001
{code}
transformed to JSON would like
{code:java}
[ {
"bill-to" : {
"street" : "123 Tornado Alley\nSuite 16\n",
"city" : "East Centerville",
"state" : "KS"
},
"ship-to" : "id001"
} ]{code}
Note how the "ship-to" does not contain the same value as "bill-to" but rather
a string with the name of the alias.
This is a known bug in Jackson as seen
[here|https://github.com/FasterXML/jackson-dataformats-text/issues/98]
The aim of this ticket is to add to the YamlTreeReader documentation the fact
that Yaml aliases are not resolved.
