Arun C Murthy commented on MAPREDUCE-3169: ------------------------------------------ Should we call it something other than MiniMRCluster to prevent confusion? > Create a new MiniMRCluster equivalent which only provides client APIs cross > MR1 and MR2 > --------------------------------------------------------------------------------------- > > Key: MAPREDUCE-3169 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3169 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: mrv1, mrv2, test > Affects Versions: 0.23.0 > Reporter: Todd Lipcon > Assignee: Ahmed Radwan > Attachments: MAPREDUCE-3169-0.20-security.patch, > MAPREDUCE-3169-0.20-security_rev2.patch, MAPREDUCE-3169-truck.patch, > MAPREDUCE-3169-trunk_rev2.patch, MAPREDUCE-3169-trunk_rev3.patch > > > Many dependent projects like HBase, Hive, Pig, etc, depend on MiniMRCluster > for writing tests. Many users do as well. MiniMRCluster, however, exposes MR > implementation details like the existence of TaskTrackers, JobTrackers, etc, > since it was used by MR1 for testing the server implementations as well. > This JIRA is to create a new interface which could be implemented either by > MR1 or MR2 that exposes only the client-side portions of the MR framework. > Ideally it would be "recompile-compatible" with MiniMRCluster for most > applications, and the MR1 implementation could be backported to 20x branch. > Thus, dependent projects like HBase could migrate to this implementation and > test against both MR1 and MR2. We can also use this to port over the current > functional tests that use only the client-side features of MiniMRCluster. -- This message is automatically generated by JIRA.
