[jira] [Created] (SPARK-20954) Describe a table showing 1 extra row
of "| # col_name | data_type | comment |"
Garros Chan created SPARK-20954:
-----------------------------------
Summary: Describe a table showing 1 extra row of "| # col_name | data_type | comment |"
Key: SPARK-20954
URL: https://issues.apache.org/jira/browse/SPARK-20954
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.1
Environment: HDP 2.5
Reporter: Garros Chan
I am trying to do DESCRIBE on a table but seeing 1 extra row being auto-added to the result. You can see there is this 1 extra row with "| # col_name | data_type | comment |"
I searched online a long time and do not find any useful information.
Is this a bug?
