https://community.cloudera.com/t5/Support-Questions/Change-data-type-of-a-field-in-schema-registry/m-p/210435#M172377 <P>Is it possible to change the type of a field in the schema registry? I created a schema in the registry, and it defaulted to backward compatibility. Right after I created it, I realized I mis-labeled one of the field types as a "long" when it was supposed to be "string." So</P><PRE>{"name": "Emp_ID", "type": "long" }</PRE><P>should instead be </P><PRE>{ "name": "Emp_ID", "type": "string"}</PRE><P>Since the schema is set to backward compatibility, if I try to create a new version with the updated type, I get an error "reader type:STRING not compatible with writer type:LONG" so I'm unable to update the schema. Since there's not really a great way to delete schemas from the registry (aside from logging directly into the backing SQL database), I was hoping to be able to update the schema so it is still usable, rather than have a bunch of junk schemas that I can't use anymore.</P><P>A colleague of mine said that with the confluent schema registry, they will disable compatibility checks, publish the new schema and then re-enable the compatibility as necessary. Is there a way to do something similar with Hortonworks Schema Registry? I haven't seen any setting that would allow me to change the compatibility mode.</P><P>Thanks</P> Sat, 07 Apr 2018 02:39:26 GMT travis_munn 2018-04-07T02:39:26Z
