-------------------------------------------

             Summary: High rate logging of BucketAllocatorException: Allocation too big 
                 Key: HBASE-26190
                 URL: https://issues.apache.org/jira/browse/HBASE-26190
             Project: HBase
          Issue Type: Bug
          Components: BucketCache, Operability
    Affects Versions: 2.4.5
            Reporter: Andrew Kyle Purtell
             Fix For: 2.5.0, 3.0.0-alpha-2, 2.4.6


These log lines may be printed at high frequency when using a schema that creates large blocks and the bucket cache is enabled. It makes sense to warn about this initially, but the very high rate of warnings when the use case is legit and this is expected does not. Print this once, then not again; or, rate-limit this message to be printed at a more reasonable rate, like once per minute.
