[jira] [Work logged] (BEAM-13470) Spanner JSON Type Not Supported When Reading Schema

     [ https://issues.apache.org/jira/browse/BEAM-13470?focusedWorklogId=710039&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-710039 ]

      Work Description: viclai opened a new pull request #16535:
URL: https://github.com/apache/beam/pull/16535


   My pipeline failed when I added the newly supported [JSON column](https://cloud.google.com/spanner/docs/working-with-json) to a Spanner table.
   
   I'm unsure if it requires more adjustments to the source code, but at this point, my pipeline is not actually reading the value of a JSON column from a Spanner table, or performing a write mutation on a JSON column.  It looks like it still fails because the full table schema has to be read for the purposes of serialization.  For now, I just want to resolve the following exception.
   
   ```
   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)
   ```
