Subject HBase MapReduce rack local MAP tasks
Date Wed, 24 Feb 2016 07:34:37 GMT
Sorry to bother. For my MapReduce framework, I split a scan into several
sub-scan of one region, however, I still got many rack-only MAP tasks rather
than data-local MAP. Is this the problem of mapred.max.split.size setting
because of hdfs defaul 64 mb block size? Or I need to use some other
taskScheduler, i.e. FairScheduler? Many thanks.
