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.

2021-08-11 23:42:10,902 WARN [main-BucketCacheWriter-0]
bucket.BucketCache: Failed allocation for
4842189251414b8a9212f6831462e415_218610843;
org.apache.hadoop.hbase.io.hfile.bucket.BucketAllocatorException:
Allocation too big size=1049337;
adjust BucketCache sizes hbase.bucketcache.bucket.sizes to accomodate
if size seems reasonable and you want it cached.
{noformat}
Also, it might be better to log this at INFO given the caveat "if size seems
reasonable and you want it cached". Reads like an informational message.
