             Summary: Spanner JSON Type Not Supported When Reading Schema
                 Key: BEAM-13470
                 URL: https://issues.apache.org/jira/browse/BEAM-13470
             Project: Beam
          Issue Type: Bug
          Components: beam-model
            Reporter: Victor Lai


Our existing data pipeline failed when we added the new [JSON column|https://cloud.google.com/spanner/docs/working-with-json] to a Spanner table that it writes to.  The following is the stack trace.
{code:java}
 Error message from worker: java.lang.IllegalArgumentException: Unknown spanner type JSON
  org.apache.beam.sdk.io.gcp.spanner.SpannerSchema$Column.parseSpannerType(SpannerSchema.java:179)
  org.apache.beam.sdk.io.gcp.spanner.SpannerSchema$Column.create(SpannerSchema.java:142)
  org.apache.beam.sdk.io.gcp.spanner.SpannerSchema$Builder.addColumn(SpannerSchema.java:74)
  org.apache.beam.sdk.io.gcp.spanner.ReadSpannerSchema.processElement(ReadSpannerSchema.java:63){code}
I included a proposed patch below that has not yet been tested.
