Izaak Rubin updated HBASE-732:
------------------------------
Attachment: hbase-732.patch
Fixes the problem of repeating text in the output of the describe command. The
problem was not specific to the describe command, but rather to any long string
that was passed through the split() method in bin/Formatter.rb. The split()
method uses Ruby's String.splice() method, which can take 2 arguments meant to
signify a starting position and a length of the substring. There was confusion
as to whether the second argument should be the length of the substring or the
ending position of the substring.
I've also added some additional tests to bin/Formatter.rb.
The tests in bin/Formatter.rb and bin/HBase.rb all passed. Standard HBase
tests were not run, as none of the actual Java code was modified.

> The formatting of the output of the shell command "describe" repeats some of
> the text. The following is an example of the problem:
> {code}
> hbase(main):001:0> describe 'table2'
> NAME => 'table2', FAMILIES => [{NAME => 'fam3', VERSIONS => 3, COMPRESSION =>
> 'NONE', IN_MEMORY => false, BLOC
> KCACHE => false, LENGTH => 2147483647, TTL => FOREVER, BLOOMFILTER => NONE},
> {NAME => 'fam2', VERSIONS => 6, COMPRESSION => 'NONE', IN_MEMORY => false,
> BLOCKCACHE => false, LENGTH => 2147483647, TTL => FOREVER, BLOOMFILT
> OMPRESSION => 'NONE', IN_MEMORY => false, BLOCKCACHE => false, LENGTH =>
> 2147483647, TTL => FOREVER, BLOOMFILTER => NONE}, {NAME => 'fam1', VERSIONS
> => 5, COMPRESSION => 'NONE', IN_MEMORY => false, BLOCKCACHE => false, LENGTH
> => 2147483647, TTL => FOREVER, BLOOMFILTER => NONE}]
> ER => NONE}, {NAME => 'fam1', VERSIONS => 5, COMPRESSION => 'NONE', IN_MEMORY
> => false, BLOCKCACHE => false, LENGTH => 2147483647, TTL => FOREVER,
