Subject Re: Loading via MapReduce, Not Moving HFiles to HBase
Date Thu, 29 Sep 2016 20:02:38 GMT
Hi Ravi,

I see in your output that the final upload of created HFiles is failing due
to the number of HFiles created per region. I also just noticed that you're
supplying the hbase.mapreduce.bulkload.max.hfiles.perRegion.perFamily
config parameter.

Could you post the exact, complete command that you're using to run this
import.

Also, be aware that overriding the max hfiles per region setting is
probably not the best way to get around this -- the fact that you've got so
many HFiles per region probably indicates that you should have more
regions. See this discussion in an earlier thread[1] for more info.
