Todd Lipcon commented on HDFS-1861:
-----------------------------------

I don't think "receiver.threads" is correct - these threads are used for both writing and reading blocks. max.transceiver.threads is probably a better name.

> Reasonably sized jobs and HBase easily exhaust the current default for dfs.datanode.max.xcievers. 4096 works better in practice.
> Let's also deprecate it in favor of a more intuitive name, eg dfs.datanode.max.receiver.threads.
