Jitter may cause desiredMaxFileSize overflow in ConstantSizeRegionSplitPolicy and trigger unexpected split

    Description

      We introduce jitter for region split decision in HBASE-13412, but the following line in ConstantSizeRegionSplitPolicy may cause long value overflow if MAX_FILESIZE is specified to Long.MAX_VALUE:

      this.desiredMaxFileSize += (long)(desiredMaxFileSize * (RANDOM.nextFloat() - 0.5D) * jitter);
      

      In our case we specify MAX_FILESIZE to Long.MAX_VALUE to prevent target region to split.

            A straight forward patch to fix the issue.

            To supplement, the region will split with small store size when overflow occurs and cause really bad perf issue.

            Another thing I'd like to mention is that currently there's no attribute in HTableDescriptor to mark a table not splittable, and we have to achieve this by specifying MAX_FILESIZE to Long.MAX_VALUE. I think we could introduce a new attribute like NEVER_SPLIT to make it much easier and straight-forward. Thoughts on this idea? If agreed, I could open another JIRA to implement it. Thanks.

            Adding UT for the overflow case, codes w/o patch will cause UT failure.

            Can this be done with DisabledRegionSplitPolicy?

            new patch trying to fix checkstyle complaint about import order. It seems eclipse's auto import organization could not pass checkstyle, I guess it expects strict dictionary order?

            Regarding the UT failures, all irrelative to the patch here. Probably introduced by HBASE-15222 and commens there already trying to fix them.

            The latest HadoopQA report looks good.

            eclark, mind take a look here since this relates to HBASE-13412? Thanks.

            Thanks for the patch carp84 The timed out tests I've added timeouts to the two that were missing them or were misconfigured. They have failed in past. Will try and work on them in another issue.

            We ran into this in 1.2 with a customer and that caused 10s of thousands of new regions to be created in matter of hours. I'm going to push it from 0.98 to 1.2

            Not pushing to 0.98 since the jitter added by HBASE-13412 is not enabled by default.

            Hi liyu, have one question about the fix. Why the overflow is only checked when (this.jitterRate > EPSILON). I modified a bit of the test case, it can get a minus desiredMaxFileSize (overflow). Should the overflow be checked for all the cases? Thanks.

              @Test
              public void testConstantSizePolicyWithJitter() throws IOException {
                conf.set(HConstants.HBASE_REGION_SPLIT_POLICY_KEY,
                  ConstantSizeRegionSplitPolicy.class.getName());
                htd.setMaxFileSize(Long.MAX_VALUE);
                boolean positiveJitter = false;
                ConstantSizeRegionSplitPolicy policy = null;
                long value = 0;
                while (value >= 0) {
                  policy = (ConstantSizeRegionSplitPolicy) RegionSplitPolicy.create(mockRegion, conf);
                  //positiveJitter = policy.positiveJitterRate();
                  value = policy.getDesiredMaxFileSize();
                  if (value < 0) {
                    System.out.println(policy.getDesiredMaxFileSize());
                    System.out.println(policy.getJitterRate());
                  }
                }
            
                // add a store
                HStore mockStore = Mockito.mock(HStore.class);
                Mockito.doReturn(2000L).when(mockStore).getSize();
                Mockito.doReturn(true).when(mockStore).canSplit();

I modified a bit of the test case, it can get a minus desiredMaxFileSize (overflow). Should the overflow be checked for all the cases? Thanks. @Test public void testConstantSizePolicyWithJitter() throws IOException { conf.set(HConstants.HBASE_REGION_SPLIT_POLICY_KEY, ConstantSizeRegionSplitPolicy. class. getName()); htd.setMaxFileSize( Long .MAX_VALUE); boolean positiveJitter = false ; ConstantSizeRegionSplitPolicy policy = null ; long value = 0; while (value >= 0) { policy = (ConstantSizeRegionSplitPolicy) RegionSplitPolicy.create(mockRegion, conf); //positiveJitter = policy.positiveJitterRate(); value = policy.getDesiredMaxFileSize(); if (value < 0) { System .out.println(policy.getDesiredMaxFileSize()); System .out.println(policy.getJitterRate()); } } // add a store HStore mockStore = Mockito.mock(HStore.class); Mockito.doReturn(2000L).when(mockStore).getSize(); Mockito.doReturn( true ).when(mockStore).canSplit(); stores.add(mockStore); // Jitter shouldn't cause overflow when HTableDescriptor.MAX_FILESIZE set to Long .MAX_VALUE assertFalse(policy.shouldSplit()); } For the failed case, values are: -9223365302346055681 (getDesiredMaxFileSize) 7.301568984985352E-7 (jitter rate)

            huaxiang I think the problem is the value of the epsilon used for the precision of the types involved (float x double). I think it should be at least 2.22e-16 (2^-52) or even 1.11e-16 (2^-53). Created HBASE-17058 for follow up. Thanks.

            Yep, both question and answer here are reasonable, and maybe we could simply use jitterRate > 0 to leave the check to JDK. Below is a simple test to confirm JDK could make a good check:

                double x = 1e-200;
                double y = -1e-200;
                System.out.println(x>0 && y<0);
            

            Thanks for committing this to branch-1.1/1.2 and opening the new issue esteban.

            huaxiang feel free to take the new JIRA if you'd like to, or I could take that if you prefer me to, just let me know (Smile).

            Agree with liyu. Or we can just check overflow if (jitterValue > 0).
