Method Detail

copyFile

public static void copyFile()
                     throws IOException

Throws:

IOException

testLateSchemaFileWildcards

public void testLateSchemaFileWildcards()

testMetadataColumns

public void testMetadataColumns()

Basic sanity test of a couple of implicit columns, along with all table columns in table order. Full testing of implicit columns is done on lower-level components.

testFullProject

public void testFullProject()

Exercise the major project operations: subset of table columns, implicit, partition, missing columns, and output order (and positions) different than table. These cases are more fully test on lower level components; here we verify that the components are wired up correctly.

testEmptyProject

public void testEmptyProject()

testMapProject

public void testMapProject()
