-------------------------------
Summary: BC capacity is not limited to 32TB
Key: HBASE-22339
URL: https://issues.apache.org/jira/browse/HBASE-22339
Project: HBase
Issue Type: Improvement
Components: BucketCache
Reporter: puleya7
{code:java}
BucketCache#constructor()：
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
blockNumCapacity >= Integer.MAX_VALUE means capacity >= 127.99TB, not 32TB
