Amar Kamat commented on MAPREDUCE-217: -------------------------------------- Except TestTaskTrackerMemoryManager (timeout), all tests have passed. Manually testing the patch. > Tasks to run on a different jvm version than the TaskTracker > ------------------------------------------------------------ > > Key: MAPREDUCE-217 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-217 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Environment: linux > Reporter: Koji Noguchi > Assignee: Amar Kamat > Attachments: mapreduce-217-v1.0.patch, mapreduce-217-v1.1.patch > > > We use 32-bit jvm for TaskTrackers. > Sometimes our users want to call 64-bit JNI libraries from their tasks. > This requires tasks to be running on 64-bit jvm. > On Solaris, you can simply use -d32/-d64 to choose, but on Linux, it's on a > completely different package. > So far, tasks run on the same jvm version as the TaskTracker. > {noformat} > // use same jvm as parent > File jvm = new File(new File(System.getProperty("java.home"), "bin"), > "java"); > {noformat} > Is it possible to let users provide a java home path > or let them choose from a pre-selected list of paths? -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
