Andrew Kyle Purtell updated HBASE-26190:
----------------------------------------
Description:
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.

adjust BucketCache sizes hbase.bucketcache.bucket.sizes to accomodate if size
seems reasonable and you want it cached.
