------------------------------
Summary: TestFSUtils flaky on hdfs getFileStatus method
Key: HBASE-6175
URL: https://issues.apache.org/jira/browse/HBASE-6175
Project: HBase
Issue Type: Bug
Components: test
Affects Versions: 0.96.0
Reporter: nkeywal
Assignee: nkeywal
Priority: Trivial
Fix For: 0.96.0
This is a simplified version of a TestFSUtils issue: a sleep and the test works
100% of the time. No sleep and it becomes flaky. Root cause unknown. While the
issue appears on the tests, the root cause could be an issue on real production
system as well.

@Test
public void testFSUTils() throws Exception {
final String hosts[] = {"host1", "host2", "host3", "host4"};
Path testFile = new Path("/test1.txt");
HBaseTestingUtility htu = new HBaseTestingUtility();
try {
htu.startMiniDFSCluster(hosts).waitActive();
FileSystem fs = htu.getDFSCluster().getFileSystem();
for (int i = 0; i < 100; ++i) {
FSDataOutputStream out = fs.create(testFile);
byte[] data = new byte[1];
out.write(data, 0, 1);
out.close();
// Put a sleep here to make me work
//Thread.sleep(2000);
FileStatus status = fs.getFileStatus(testFile);
HDFSBlocksDistribution blocksDistribution =
FSUtils.computeHDFSBlocksDistribution(fs, status, 0, status.getLen());
assertEquals("Wrong number of hosts distributing blocks. at
iteration "+i, 3,
blocksDistribution.getTopHosts().size());
fs.delete(testFile, true);
}
} finally {
htu.shutdownMiniDFSCluster();
}
}
