stack commented on HBASE-6283:
------------------------------
This should IOError or whatever the ruby equiv of FNFE is:
{code}
+ if ! File.exist?(filename)
+ return java.util.ArrayList.new()
..
{code}
... rather than just return empty array?
Else looks good to me.
Does this change relate to Aravind's work? See down in his blog where he says:
"The region_mover.rb script is an extension of the standard region_mover.rb
that ships with stock HBase. I hacked it a little to add slow balancing support
and automatic region balancing while unloading regions from a server. This
version is also aware of draining servers and avoids them during region
assignment and balancing. Again, look for the older commit if you want to use
this with 0.90.x HBase releases. The latest version is for the 0.92 release."

> [region_mover.rb] Add option to exclude list of hosts on unload instead of

> Currently, the region_mover.rb script excludes a single host, the host
> offloading data, as a region move target. This essentially limits the number
> of machines that can be shutdown at a time to one. For larger clusters, it
> is manageable to have several nodes down at a time and desirable to get this
> process done more quickly.
> The proposed patch adds an exclude file option, that allows multiple hosts to
> be excluded as targets.
