类 AliHBaseIndexDescriptor

java.lang.Object

org.apache.hadoop.hbase.client.index.AliHBaseIndexDescriptor

public class AliHBaseIndexDescriptor
extends Object

Similar to HTableDescriptor, describes an index table. Clients should use this descriptor to create an index. TODO: index descriptor may not extends all attributes from table descriptor
