> replace HTableDescriptor#htd.getColumnFamilies().length with a low-cost

> Key: HBASE-17245
> URL: https://issues.apache.org/jira/browse/HBASE-17245
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: huaxiang sun
> Assignee: huaxiang sun
> Priority: Minor
> Attachments: HBASE-17245-master-001.patch
>
>
> Found quite a few places doing something like
> {code}
> if (htd.getColumnFamilies().length == 0) {
> {code}
> HTableDescriptor#htd.getColumnFamilies() does a few memory allocations. The
> purpose is to get the family number, it can be replaced with
> {code}
> + public int getColumnFamilyCount() {
> + return families.size();
> + }
> {code}
> in HTableDescriptor which does not need these memory allocations.
