Description
Log statements from the InputFormat or anywhere else in the hadoop client / submitter seem to get buffered until the MR job completes, instead of printing as the job progresses.

Research direction
No files or tests are named. Start by tracing logging from the InputFormat and Hadoop client or submitter during a running MapReduce job, then compare when those messages become visible. Done means client-side log statements print as the job progresses rather than only after completion.
