-----------------------------------
Summary: MySQL thirdparty tests hang if there's no USER
environment variable
Key: SQOOP-3283
URL: https://issues.apache.org/jira/browse/SQOOP-3283
Project: Sqoop
Issue Type: Bug
Components: connectors/mysql, test
Affects Versions: 1.4.7
Reporter: Daniel Voros
Assignee: Daniel Voros
{{org.apache.sqoop.manager.mysql.MySQLTestUtils#getCurrentUser()}} executes
{{whoami}} in a subprocess if there's no USER environment variable (happened to
me while running tests from Docker). However, it waits for the Process variable
to become null, that never happens:
{code:java}
// wait for whoami to exit.
while (p != null) {
try {
int ret = p.waitFor();
if (0 != ret) {
LOG.error("whoami exited with error status " + ret);
// suppress original return value from this method.
return null;
}
} catch (InterruptedException ie) {
continue; // loop around.
}
}
{code}
We could get rid of the while loop since {{Process#waitFor()}} blocks while it
completes.
Note, that it's easy to workaround the issue by setting the USER environment
variable when running the tests.
