Mingliang Liu created HBASE-20932: ------------------------------------- Summary: Effective MemStoreSize::hashCode() Key: HBASE-20932 URL: https://issues.apache.org/jira/browse/HBASE-20932 Project: HBase Issue Type: Bug Affects Versions: 2.0.2 Reporter: Mingliang Liu
After [HBASE-20411] we have {code:title=MemStoreSize::hashCode()} @Override public int hashCode() { long h = 31 * this.dataSize; h = h + 31 * this.heapSize; h = h + 31 * this.offHeapSize; return (int) h; {code} This is not effective {{hashCode()}} implementation. Instead we can use: {code:title=MemStoreSize::hashCode()} @Override public int hashCode() { long h = 31 * this.dataSize; h = h * 31 + this.heapSize; h = h * 31 + this.offHeapSize; return (int) h; {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
