>                 URL: https://issues.apache.org/jira/browse/HBASE-22339
>             Project: HBase
>          Issue Type: Improvement
>          Components: BucketCache

> In the constructor of BC, the capacity limit looks like 32TB, code as follow:
>  
> {code:java}
> long blockNumCapacity = capacity / blockSize;
> if (blockNumCapacity >= Integer.MAX_VALUE) {
>   // Enough for about 32TB of cache!
>   throw new IllegalArgumentException("Cache capacity is too large, only support 32TB
now");
> }
> {code}
> Default blockSize is 64*1024
> Integer.MAX_VALUE is 2147483647
> blockNumCapacity >= Integer.MAX_VALUE means capacity >= 127.99TB, not 32TB.
