[jira] Commented: (HADOOP-1611) [hbase] Add enableTable,
disableTable, addColumn, etc, to shell
[ https://issues.apache.org/jira/browse/HADOOP-1611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12527196 ]
stack commented on HADOOP-1611:
-------------------------------
HADOOP-1720 adds 'alter table'. Using it, you can add/delete columns. It runs the disable/enable of the table for you.
The 'alter table' also has notion of 'change' for column families to set column family attributes but currently its unimplemented.
That leaves enable/disable table, merge of two adjacent regions (Specifying regexes on selects belongs in an another issue).

> Key: HADOOP-1611
> URL: https://issues.apache.org/jira/browse/HADOOP-1611
> Project: Hadoop
> Issue Type: Sub-task
> Components: contrib/hbase
> Reporter: stack
> Priority: Minor
>
> Here are some nice-to-have admin functions that would sit nicely in hbase shell:
> + public void addColumn(Text tableName, HColumnDescriptor column) throws IOException;
> + public void deleteColumn(Text tableName, Text columnName) throws IOException;
> +
> + public void enableTable(Text tableName) throws IOException;
> + public void disableTable(Text tableName) throws IOException;
> (To add/delete columns you must first disable the table and then reenable it).
> Other possibles:
> + public void mergeRegions(Text regionName1, Text regionName2) throws IOException;
> + Allow specification of basic row filtering (Doesn't have to be exotic): regex match, upper limit on rows returned.
> + Allow changing versions on column families, enabling/disabling compression, bloom filters
