Subject Are hadoop fs commands serial or parallel
Date Wed, 18 May 2011 00:44:27 GMT
My question is when I run a command from hdfs client, for eg. hadoop fs
-copyFromLocal or create a sequence file writer in java code and append
key/values to it through Hadoop APIs, does it internally transfer/write data
to HDFS serially or in parallel ?

Thanks in advance,
