Re: TaskStatus Exception using HFileOutputFormat

Ahh yes, sorry I left that out:

Hadoop: 1.0.3
HBase: 0.92.0
> I guess you have used the above construct
Our code is as follows:
HTable table = new HTable(conf, configHBaseTable);
FileOutputFormat.setOutputPath(job, outputDir);
HFileOutputFormat.configureIncrementalLoad(job, table);
Thanks!

Can you tell us the HBase and hadoop versions you were using ?
>From TestHFileOutputFormat:

    HFileOutputFormat.configureIncrementalLoad(job, table);

    FileOutputFormat.setOutputPath(job, outDir);

I guess you have used the above construct ?

Cheers

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
