> I recently ran into a problem in {{TaskCommitContextRegistry}}, when using dynamic-partitions.
> Consider a MapReduce program that reads HCatRecords from a table (using HCatInputFormat), and then writes to another table (with identical schema), using HCatOutputFormat. The Map-task fails with the following exception:
> {code}
> Error: java.io.IOException: No callback registered for TaskAttemptID:attempt_1426589008676_509707_m_000000_0@hdfs://crystalmyth.myth.net:8020/user/mithunr/mythdb/target/_DYN0.6784154320609959/grid=__HIVE_DEFAULT_PARTITION__/dt=__HIVE_DEFAULT_PARTITION__

> {{TaskCommitContextRegistry::commitTask()}} uses call-backs registered from {{DynamicPartitionFileRecordWriter}}. But in case {{HCatInputFormat}} and {{HCatOutputFormat}} are both used in the same job, the {{DynamicPartitionFileRecordWriter}} might only be exercised in the Reducer.
> I'm relaxing the IOException, and log a warning message instead of just failing.
> (I'll post the fix shortly.)
