Koji Noguchi commented on HADOOP-3016:
--------------------------------------
Request from Don,
" Given how often our nodes have problems, we find ourselves using the
dfs.host.exclude file
quite a bit to list out "broken" nodes so that they can't be used in the
cluster.
We were wondering, can we have the ability to add comments in the
dfs.host.exclude file,
an ability to use lines that start with "#" which get ignored? That way
when we have a couple dozen
machines listed in dfs.host.exclude file, we can put comments in there as to
why they are out of rotation. "
