Todd Lipcon commented on HDFS-1055:
-----------------------------------
It's not top of my list - if you wanted to merge our two patches and post a
patch against trunk, that would be great. Otherwise I will likely get to this
some time in May.
> Improve thread naming for DataXceivers
> --------------------------------------
>
> Key: HDFS-1055
> URL: https://issues.apache.org/jira/browse/HDFS-1055
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: data-node
> Affects Versions: 0.22.0
> Reporter: Todd Lipcon
> Attachments: dataxceiver.patch, hdfs-1055-branch20.txt
>
>
> The DataXceiver threads are named using the default Daemon naming, which is
> Runnable.toString(). Currently this isn't implemented, so threads have names
> like org.apache.hadoop.hdfs.server.datanode.dataxcei...@579c9a6b. It would be
> very handy for debugging (and even ops maybe) to have a better name like
> "DataXceiver for client 1.2.3.4 [reading block_234254242]"
