Reproduced this test failure locally. A proper fix for this issue can be:
```scala
withSQLConf(HiveContext.CONVERT_METASTORE_PARQUET.key -> "false") {
checkExistence(sql("DESC EXTENDED ctas5"), true,
"name:key", "type:string", "name:value", "ctas5",
"org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat",
"org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat",
"org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe",
"MANAGED_TABLE"
)
}
```
The reason is that, the `MetastoreRelation` in `DESC EXTENDED ctas5` is
converted to a Parquet data source table.
@viirya I'm going to open a new PR to fix this issue since it is probably
breaking the PR builder. Will attribute the new PR to you. Thanks for bringing
up and investigating this issue!
