[jira] [Commented] (HBASE-4115) HBase shell assign and unassign unusable if region name includes binary-encoded data

["stack (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-4115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067557#comment-13067557 ] 

stack commented on HBASE-4115:
------------------------------

Is this right Ryan? I thought the UI already escaped region names that comprised binary data?  It used to be the case -- perhaps since broken -- where you could copy what was into the UI and then as long as you double-quoted it, it'd work.  Here is snippet from shell help:

{code}
If you are using binary keys or values and need to enter them in the shell, use
double-quote'd hexadecimal representation. For example:

  hbase> get 't1', "key\x03\x3f\xcd"
  hbase> get 't1', "key\003\023\011"
  hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"
{code}

hbck should print out escaped binary but I would not be surprised if it did not... so here you should be able to copy it into shell and double-quote it and it'd work (If you single-quote it, the shell does not interpret the bytes IIRC).

So you are pasting actual binary data into the shell?

Thanks.

> When using the hbase shell assign and unassign commands, we should be able to copy region names from the hbck utility or the web page hosted by the HMaster process.  But if these names have encoded binary data, they region name won't match and the command will fail.
> This is easily fixed by using Bytes.toBytesBinary on the region name in these commands rather than the raw Bytes.ToBytes.
