Oleg Zinoviev updated DRILL-7349:
---------------------------------
Description:
ClusterTest#dirTestWatcher works inconsistent if cluster size is greater when 1.
For example, test
{code:java}
public class TestClusterTest extends ClusterTest {
@BeforeClass
public static void setUp() throws Exception {
startCluster(ClusterFixture.builder(dirTestWatcher).clusterSize(2));
}
@Test
public void testWriteFile() throws Exception {
final String outputFileName = "some_file_name";
final File outputFile =
FileUtils.getFile(dirTestWatcher.getDfsTestTmpDir(), outputFileName);
queryBuilder().sql("CREATE TABLE dfs.tmp.%s AS SELECT * FROM
cp.`employee.json` limit 1", outputFileName).run();
assertTrue(outputFile.exists());
}
}
{code}
may fail on assertion.
Reason: several directories for the storage `dfs.tmp` (possibly 1 for each
node) was created, and dirTestWatcher.getDfsTestTmpDir () may return the wrong
one.
