Andrew Purtell commented on HBASE-17714:
----------------------------------------
e5c1a80 (HBASE-15645 hbase.rpc.timeout is not used in operations of HTable) is
the commit that causes RenewLeaseIT to start failing. You have to apply
HBASE-16420 (Fix source incompatibility of Table interface) after checking out
e5c1a80 to get something that 4.x-HBase-1.1 will compile against.
HBASE-15645 was shipped in 1.1.5, 1.2.2, and 1.3.0.
What this change does is fix where the client was not actually honoring RPC
timeouts prior to the change. [~samarthjain] are you sure RenewLeaseIT actually
renews the lease before the RPC times out? The test sets a very short RPC
timeout (2000ms)
> Client heartbeats seems to be broken

> 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.
