> HBASE-11083 allows ExportSnapshot to limit bandwidth usage.
> Here is *one* approach for backporting:
> Create the following classes (class name is tentative):
> hbase-hadoop1-compat/src/main/java/org/apache/hadoop/hbase/util/ThrottledInputStream.java
> hbase-hadoop2-compat/src/main/java/org/apache/hadoop/hbase/util/ThrottledInputStream.java
> each of which extends the corresponding ThrottledInputStream in hadoop-1 / hadoop-2
> ExportSnapshot would reference util.ThrottledInputStream, depending on which compatibility
module gets bundled.
> ThrottledInputStream.java in hadoop-1 branch was backported through MAPREDUCE-5081 which
went into 1.2.0 release.
> We need to decide how hadoop releases earlier than 1.2.0 should be supported.
> *Second* approach for backporting is to make a copy of ThrottledInputStream and include
it in hbase codebase.
