Subject [jira] [Created] (HBASE-17494) Guard against cloning family of all cells if no data need be replicated
Date Thu, 19 Jan 2017 19:02:26 GMT
ChiaPing Tsai created HBASE-17494:
-------------------------------------

             Summary: Guard against cloning family of all cells if no data need be replicated
                 Key: HBASE-17494
                 URL: https://issues.apache.org/jira/browse/HBASE-17494
             Project: HBase
          Issue Type: Improvement
            Reporter: ChiaPing Tsai
            Priority: Trivial


The replication is enabled by default, so we try to clone the family of all cells even if
there is no replication at all.
{noformat}
  family = CellUtil.cloneFamily(cell);
  // Unexpected, has a tendency to happen in unit tests
  assert htd.getFamily(family) != null;

  if (!scopes.containsKey(family)) {
  int scope = htd.getFamily(family).getScope();
  if (scope != REPLICATION_SCOPE_LOCAL) {
  scopes.put(family, scope);
  }
  }
{noformat}

HBASE-15205 had resolved this issue, but it is committed to master only.
