[jira] [Created] (ZEPPELIN-733) SparkSqlInterpreter fails to
execute query with spark-csv
Raphaël Luta created ZEPPELIN-733:
-------------------------------------
Summary: SparkSqlInterpreter fails to execute query with spark-csv
Key: ZEPPELIN-733
URL: https://issues.apache.org/jira/browse/ZEPPELIN-733
Project: Zeppelin
Issue Type: Bug
Components: Interpreters, zeppelin-interpreter
Affects Versions: 0.6.0
Environment: spark 1.6.0
spark-csv 1.3.0
Reporter: Raphaël Luta
If I run this code in a spark interpreter cell
```
val df = sqlContext.read.format("com.databricks.spark.csv").load("mycsv")
df.registerTempTable("testbug")
```
and then run this code in a new %spark cell:
```
println("%table\nC0\n")
sqlContext.sql("""select * from testbug""").collect().take(100).map(_.getString(0)).foreach(println)
```
I get the expected result displayed in a Zeppelin table, however if I run in a new %sql cell:
```
%sql
select * from testbug
```
I get the following stacktrace:
```

```
Expected result is that the %sql cell should produce the same result as the manual spark formatting.
Notes:
This bug does not manifest if the DataFrame is cached before executing the SELECT statement
