----------------------------------------
Summary: Transform spec literals should be checked during validate
Key: SYSTEMML-1840
URL: https://issues.apache.org/jira/browse/SYSTEMML-1840
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Currently, there is no validation happening for transform specifications during
initial compilation. This is very annoying, especially when trying to encode
large files, which takes a while to read in, just to find out that the given
transform specification was invalid json. Here is an example:
{code}
Caused by: org.apache.wink.json4j.JSONException: Expecting '{' on line 1,
column 4 instead, obtained token: 'Token: String - 'ids''
at org.apache.wink.json4j.internal.Parser.parseObject(Parser.java:193)
at org.apache.wink.json4j.internal.Parser.parse(Parser.java:130)
at org.apache.wink.json4j.internal.Parser.parse(Parser.java:95)
at org.apache.wink.json4j.JSONObject.<init>(JSONObject.java:138)
at
org.apache.sysml.runtime.transform.encode.EncoderFactory.createEncoder(EncoderFactory.java:56)
{code}
This task aims to parse the transform specification if its available as a
literal string during the language validation step.
