----------------------------------
Summary: Unit tests fail in Eclipse because source is not on class
path
Key: DRILL-6015
URL: https://issues.apache.org/jira/browse/DRILL-6015
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.12.0
Reporter: Paul Rogers
Using Eclipse, attempt to run TestJsonReader as a JUnit test. Many test cases
fail with the following error:
{noformat}
12:17:38.791 [main] ERROR org.apache.drill.TestReporter - Test Failed (d: 0 B(1
B), h: 23.5 MiB(150.0 MiB), nh: 14.7 MiB(71.2 MiB)):
drill_4479(org.apache.drill.exec.vector.complex.writer.TestJsonReader)
java.lang.Exception: org.apache.drill.common.exceptions.UserRemoteException:
FUNCTION ERROR: Failure reading Function class.
Function Class:
org.apache.drill.exec.expr.fn.impl.gaggr.CountFunctions$BigIntCountFunction
Fragment: 0:0
(java.io.IOException) Failure trying to locate source code for class
org.apache.drill.exec.expr.fn.impl.gaggr.CountFunctions$BigIntCountFunction,
tried to read on classpath location
/org/apache/drill/exec/expr/fn/impl/gaggr/CountFunctions.java
{noformat}
As noted in the message, the Drill source code (at least for functions) must be
on the class path. But, this is an unusual configuration, and requires that
sources be copied to target directory as resources.
The workaround is to manually add the required class path entry for each test
run in Eclipse. This is error prone and tedious as a typical debug session may
run a dozen individual test cases, each of which needs its own configuration.
