Subject [jira] [Created] (POOL-313) Code generation fails when running SQL expressions against a wide dataset (thousands of columns)

---------------------------------------

             Summary: Code generation fails when running SQL expressions against a wide dataset
(thousands of columns)
                 Key: POOL-313
                 URL: https://issues.apache.org/jira/browse/POOL-313
             Project: Commons Pool
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Iaroslav Zeigerman


When reading the CSV file that contains 1776 columns Spark and Janino fail to generate the
code with message:
{noformat}
Constant pool has grown past JVM limit of 0xFFFF
{noformat}

When running a common select with all columns it's fine:
{code}
      val allCols = df.columns.map(c => col(c).as(c + "_alias"))
      val newDf = df.select(allCols: _*)
      newDf.show()
{code}

But when I invoke the describe method:
{code}
newDf.describe(allCols: _*)
{code}

it fails with the following stack trace:
