------------------------------

             Summary: Backport HBASE-11083 ExportSnapshot should provide capability to limit
bandwidth consumption
                 Key: HBASE-11090
                 URL: https://issues.apache.org/jira/browse/HBASE-11090
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu


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.
