-----------------------------------
Summary: Make sure that Derby is shut down after each testcase
Key: OOZIE-3296
URL: https://issues.apache.org/jira/browse/OOZIE-3296
Project: Oozie
Issue Type: Sub-task
Reporter: Peter Bacsko
Assignee: Peter Bacsko
Currently we use in-memory HSQLDB for Oozie tests. However, if we switch to
Derby, we can't run all tests in a single suite because we'll get "Too many
open files" error.
This happens before every testcase creates its own Derby instance and the
previous one is not shut down properly. A single Derby instance opens around
40-50 files, so the number of open files keep accumulating.
The following code ensures that Derby is closed after each test:
{noformat}
final String oozieTestDB = System.getProperty("oozie.test.db", "derby");
if (oozieTestDB.equalsIgnoreCase("derby")) {
try {
String jdbcUrl = "jdbc:derby:" + testCaseDir +
"/oozie-derby;shutdown=true";
java.sql.Connection conn = DriverManager.getConnection(jdbcUrl);
conn.close();
} catch (Exception e) {
log.info(e);
}
}
{noformat}
