[jira] Commented: (HADOOP-933) Application defined InputSplits do
not work
[ https://issues.apache.org/jira/browse/HADOOP-933?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12467513 ]
Hadoop QA commented on HADOOP-933:
----------------------------------
-1, because the patch command could not apply the latest attachment (http://issues.apache.org/jira/secure/attachment/12349621/MapTask.patch) as a patch to trunk revision r499156. Please note that this message is automatically generated and may represent a problem with the automation system and not the patch.

> If an application defines its own InputSplit, the task tracker chokes when it cannot deserialize the InputSplit when it deserializes MapTasks it receives from the JobTracker. This is because the TaskTracker does not resolve classes from the job jar file. The attached patch delays resolution of the InputSplit until it is running in the context of the child process where it can resolve the InputSplit class.

The patch couldn't be applied by the automated process because the
filename in the patch did not start with src/java/org/...
