Re: TaskStatus Exception using HFileOutputFormat
Ted Yu 2013-02-06, 00:46
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
