Samarth Jain created HBASE-17714: ------------------------------------ Summary: Client heartbeats seems to be broken Key: HBASE-17714 URL: https://issues.apache.org/jira/browse/HBASE-17714 Project: HBase Issue Type: Bug Reporter: Samarth Jain
We have a test in Phoenix where we introduce an artificial sleep of 2 times the RPC timeout in preScannerNext() hook of a co-processor. {code} public static class SleepingRegionObserver extends SimpleRegionObserver { public SleepingRegionObserver() {} @Override public boolean preScannerNext(final ObserverContext<RegionCoprocessorEnvironment> c, final InternalScanner s, final List<Result> results, final int limit, final boolean hasMore) throws IOException { try { if (SLEEP_NOW && c.getEnvironment().getRegion().getRegionInfo().getTable().getNameAsString().equals(TABLE_NAME)) { Thread.sleep(RPC_TIMEOUT * 2); } } catch (InterruptedException e) { throw new IOException(e); } return super.preScannerNext(c, s, results, limit, hasMore); } } {code} This test was passing fine till 1.1.3 but started failing sometime before 1.1.9 with an OutOfOrderScannerException. See PHOENIX-3702. [~lhofhansl] mentioned that we have client heartbeats enabled and that should prevent us from running into issues like this. FYI, this test fails with 1.2.3 version of HBase too.
