Subject [jira] Commented: (HADOOP-1001) the output of the map is not type checked against the specified types

Tahir Hashmi commented on HADOOP-1001:
--------------------------------------

Oh yes, reporting the expected and received type names is the right thing to do :)

Besides trying to print them, is there a better way of reporting some information about which
key/value pair triggered the error? The mapper may have some conditional code-paths that generate
correctly typed pairs some times and incorrect pairs other times. Knowing which key/value
triggered the error could help locating such code.
