mingfang commented on issue #4890: [pulsar-sql] Handle schema not found URL: https://github.com/apache/pulsar/pull/4890#issuecomment-524159615 I'm not sure it this is related but I'm seeing the "Table has no columns" error when running the Pulsar SQL tutorial here https://pulsar.apache.org/docs/en/sql-getting-started/. Steps to recreate the problem 1-Generate some data by running this command for a minute and then kill it. `./bin/pulsar-admin sources localrun --name generator --destinationTopicName generator_test -a connectors/pulsar-io-data-generator-2.4.0.nar` 2-Use Pulsar SQL to "consume" the data `select * from pulsar."public/default".generator_test;` 3-Repeat steps 1 and 2. In step 2 I would see this error `Query 20190823_033331_00067_sw7tk failed: Table has no columns: pulsar:PulsarTableHandle{connectorId=pulsar, schemaName=public/default, tableName=generator_test, topicName=generator_test}` I can reproduce this error 100% of the time.
