Subject TaskStatus Exception using HFileOutputFormat
Date Wed, 06 Feb 2013 00:31:24 GMT

We're trying to use HFileOutputFormat for bulk hbase loading.   When using HFileOutputFormat's
setOutputPath or configureIncrementalLoad, the job is unable to run.  The error I see in the
jobtracker logs is: Trying to set finish time for task attempt_201301030046_123198_m_000002_0
when no start time is set, stackTrace is : java.lang.Exception

If I remove an references to HFileOutputFormat, and use FileOutputFormat.setOutputPath, things
seem to run great.  Does anyone know what could be causing the TaskStatus error when using
HFileOutputFormat?

Thanks,

Sean
