Ted Yu created HBASE-8240:
-----------------------------
Summary: CompoundConfiguration should implement Iterable
Key: HBASE-8240
URL: https://issues.apache.org/jira/browse/HBASE-8240
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Here is from hadoop Configuration class:
{code}
public class Configuration implements Iterable<Map.Entry<String,String>>,
{code}
There're 3 addXX() methods for CompoundConfiguration:
{code}
public CompoundConfiguration add(final Configuration conf) {
public CompoundConfiguration addWritableMap(
final Map<ImmutableBytesWritable, ImmutableBytesWritable> map) {
public CompoundConfiguration addStringMap(final Map<String, String> map) {
{code}
Parameters to these methods all support iteration.
We can enhance ImmutableConfigMap with the following new method:
{code}
public abstract java.util.Iterator iterator();
{code}
This enhancement would be useful in scenario where a mutable Configuration is
required.
