> Key: HDFS-375
> URL: https://issues.apache.org/jira/browse/HDFS-375
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Runping Qi
>
> When we do dfs throughput test using hadoop dfs -cat, we have observed that
> the client side cpu usage is very high, 3 to five times that of a data node
> serving the file.
> Before 0.18, the data node cpu usage was equally high, and this problem is
> fixed since 0.18. However, the client side problem still exists.
