[jira] [Created] (HBASE-8290) TestHTableMultiplexer is flaky
Nicolas Liochon created HBASE-8290:
--------------------------------------
Summary: TestHTableMultiplexer is flaky
Key: HBASE-8290
URL: https://issues.apache.org/jira/browse/HBASE-8290
Project: HBase
Issue Type: Bug
Components: test
Affects Versions: 0.95.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Fix For: 0.95.1
I reproduce it all the time if I comment the sleep here:
{code}
private void verifyAllBufferedPutsHaveFlushed(HTableMultiplexerStatus status) {
int retries = 8;
int tries = 0;
do { /*
try {
Thread.sleep(2 * TEST_UTIL.getConfiguration().getLong(
HTableMultiplexer.TABLE_MULTIPLEXER_FLUSH_FREQ_MS, 100));
tries++;
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
} */
} while (status.getTotalBufferedCounter() != 0 && tries != retries);
assertEquals("There are still some buffered puts left in the queue",
0, status.getTotalBufferedCounter());
}
{code}
Given that getTotalBufferedCounter is never decremented, there is a misunderstanding somewhere. As well, reading plain values without a volatile or a synchronized in a MT context is likely to be wrong.
