Ryan Thiessen commented on HBASE-4756:
--------------------------------------
A simple example:
org<tab>
longer example:
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.HConstants
import org.apache.hadoop.hbase.client.HBaseAdmin
import org.apache.hadoop.hbase.util.Bytes
config = HBaseConfiguration.new
config.set 'fs.default.name', config.get(HConstants::HBASE_DIR)
admin = HBaseAdmin.new(config)
row = scanner = admin.listTables[0]
row.getFamilies.<tab>
> Enable tab-completion in HBase shell
> ------------------------------------

> Key: HBASE-4756
> URL: https://issues.apache.org/jira/browse/HBASE-4756
> Project: HBase
> Issue Type: Improvement
> Components: shell
> Reporter: Ryan Thiessen
> Priority: Minor
>
> Tab-completion in the HBase irb shell is nifty for debugging. Without the
> +X-O option it frequently crashes. Is there any reason not to enable this by
> default?
> This would be as simple as:
> - CLASS="org.jruby.Main ${HBASE_HOME}/bin/hirb.rb"
> + CLASS="org.jruby.Main -X+O ${HBASE_HOME}/bin/hirb.rb"
