ChunHao reassigned HBASE-17399:
-------------------------------
Assignee: ChunHao
> region_mover.rb uses different default filename, also needs slight change
> -------------------------------------------------------------------------
>
> Key: HBASE-17399
> URL: https://issues.apache.org/jira/browse/HBASE-17399
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.3.0
> Reporter: Lars George
> Assignee: ChunHao
> Labels: beginner
>
> The command line help prints:
> {noformat}
> -f, --filename=FILE File to save regions list into unloading, \
> or read from loading; default /tmp/<hostname:port>
> {noformat}
> while in reality, the code does this:
> {code}
> def getFilename(options, targetServer, port)
> filename = options[:file]
> if not filename
> filename = "/tmp/" + ENV['USER'] + targetServer + ":" + port
> end
> return filename
> end
> {code}
> An example for a generated file is:
> {noformat}
> /tmp/larsgeorgeslave-3.internal.larsgeorge.com\:16020
> {noformat}
> I suggest we fix the command line help explanation. But first, we should also
> fix how the name is generated, *adding* a divider between the user name and
> the host name, and also change how the port is attached to the host name.
> Currently this results in a rather strange {{\:}} which could be hard to
> handle. Maybe we simply use an exclamation mark or hash for both? For example:
> {noformat}
> /tmp/larsgeorge!slave-3.internal.larsgeorge.com!16020
> /tmp/larsgeorge#slave-3.internal.larsgeorge.com#16020
> {noformat}
