Vinayakumar B commented on HDFS-9067:
-------------------------------------
{code}
- protected void waitForMetric(final String metricName, final int
expectedValue)
- throws TimeoutException, InterruptedException {
- GenericTestUtils.waitFor(new Supplier<Boolean>() {
- @Override
- public Boolean get() {
- try {
- final int currentValue = Integer.parseInt(jmx.getValue(metricName));
- LOG.info("Waiting for " + metricName +
- " to reach value " + expectedValue +
- ", current value = " + currentValue);
- return currentValue == expectedValue;
- } catch (Exception e) {
- throw new UnhandledException("Test failed due to unexpected
exception", e);
- }
- }
- }, 1000, Integer.MAX_VALUE);
- }
-{code}
I think instead of above complete removal of method, you can call
{{DFSTestUtil#waitforMetric(..)}} from here, so that changes in other files
need not be required.
