      Description

      From CDAP Hydrator UI, build a pipeline:

      • Select one of the available batch sources (for example, TPFSAvro).
      • From the Dataset Name field, select a dataset from the dropdown list.
      • The dataset exists. The popup "....Are you sure you want to continue?", click the yes.
      • On the left hand side, under the Output Schema section, it shows the output schema as "No schema Available"

      The 1st problem is the "No schema Available". Not sure why it can not find the schema. May be it is too big. The schema has 41 fields. There is no problem for a smaller schema which has 4 fields.

      The 2nd problem, fr ome the "Actions" drop down menu, the "import" is not available when it can not find the schema. I think, at this situation, it should be made available. In addition, not all datasets are made exploreable and they have no schema defined.
