Enis Soztutar commented on HADOOP-9660:
---------------------------------------
I've noticed that in HBase, we still have a lot of classes which accept their
arguments in --key=value or --key=val1,val2,val3 or similar formats. I had
opened HBASE-8901 for tracking this, in which I created a small .ps1 script to
pre-parse the arguments. Can you please take a look at that to see whether that
makes sense or not.
> [WINDOWS] Powershell / cmd parses -Dkey=value from command line as [-Dkey,
> value] which breaks GenericsOptionParser

> When parsing parameters to a class implementing Tool, and using ToolRunner,
> we can pass
> {code}
> bin/hadoop <tool_class> -Dkey=value
> {code}
> However, powershell parses the '=' sign itself, and sends it to java as
> ["-Dkey", "value"] which breaks GenericOptionsParser.
> Using "-Dkey=value" or '-Dkey=value' does not fix the problem. The only
> workaround seems to trick PS by using:
> '"-Dkey=value"' (single + double quote)
> In cmd, "-Dkey=value" works, but not '"-Dkey=value"'.
