Subject [jira] Commented: (HBASE-1363) Can't use 'close region' when keys are binary
Date Tue, 09 Jun 2009 21:17:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12717821#action_12717821

Lars George commented on HBASE-1363:
------------------------------------

So it looks like the JRuby shell does not handle binary character notations. I have instrumented
the shell to print out what it gets and do the same on he HRegion.get():

{code}
Shell:
hbase(main):002:0> get '.META.', 'TestTable,\000\000\000\000\002\000\003\005\002\000,1244575397228'
row: TestTable,\000\000\000\000\002\000\003\005\002\000,12445753972280 row(s) in 0.0080 seconds

HRegion:
2009-06-09 23:11:48,694 DEBUG org.apache.hadoop.hbase.regionserver.HRegion: @@@ row: TestTable,\x5C000\x5C000\x5C000\x5C000\x5C002\x5C000\x5C003\x5C005\x5C002\x5C000,1244575397228
{code}

or

{code}
Shell:
hbase(main):004:0> get '.META.', 'TestTable,\x00\x00\x00\x00\x02\x00\x03\x05\x02\x00,1244575618625'
row: TestTable,\x00\x00\x00\x00\x02\x00\x03\x05\x02\x00,12445756186250 row(s) in 0.0180 seconds

HRegion:
2009-06-09 23:16:02,271 DEBUG org.apache.hadoop.hbase.regionserver.HRegion: @@@ row: TestTable,\x5Cx00\x5Cx00\x5Cx00\x5Cx00\x5Cx02\x5Cx00\x5Cx03\x5Cx05\x5Cx02\x5Cx00,1244575618625
{code}

> maybe we should allow you to use an encoded name to close a region, or use binary escaping.
