Subject [jira] [Commented] (HBASE-8408) Implement namespace
Date Mon, 05 Aug 2013 21:32:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13729981#comment-13729981

stack commented on HBASE-8408:
------------------------------

Trying the patch, LoadTestTool is only hunk that would not apply (Easy fix of an import).
 Also has prob w/

b/hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/wal/TestLogRollAbort.java

This pretty brutal in the shell:

{code}
hbase(main):002:0> scan '.META.'

ERROR: java.lang.IllegalArgumentException: Illegal first character <46> at 0. Namespaces
can only start with alphanumeric characters': i.e. [a-zA-Z_0-9]: .META.

Here is some help for this command:
Scan a table; pass table name and optionally a dictionary of scanner
specifications.  Scanner specifications may include one or more of:
TIMERANGE, FILTER, LIMIT, STARTROW, STOPROW, TIMESTAMP, MAXLENGTH,
or COLUMNS, CACHE....
{code}

Should probably give folks a bit of a nicer letdown.

If I do 'list', I do not see system tables and the help gives me no clue they exist.  I suppose
this is how it always was.

Should I be able to do this?

hbase(main):013:0> create 'hbase:stack', 'stack'
0 row(s) in 0.1790 seconds

I created a system table named 'stack'?

The 'create' command needs updating so  it has some namespace stuff going on?  Doesn't it?
 It has nothing on it currently.
