[jira] [Commented] (HBASE-9275) shell "list" includes
"hbase:namespace"
[ https://issues.apache.org/jira/browse/HBASE-9275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13745479#comment-13745479 ]
Nick Dimiduk commented on HBASE-9275:
-------------------------------------
I propose the shell be updated to invoke {{HMaster#getTableDescriptors}} and the logic common to the two method be refactored into a helper method so that both share the same implementation.
Please advise.

> Key: HBASE-9275
> URL: https://issues.apache.org/jira/browse/HBASE-9275
> Project: HBase
> Issue Type: Bug
> Components: shell
> Affects Versions: 0.95.2
> Reporter: Nick Dimiduk
> Priority: Minor
>
> From the shell "list" operation, we see the "user:namespace" table included in results. This is different from retrieving a tabling listing from the REST service, which omits that table.
> The reason appears to be that hbase shell "list" command calls the deprecated {{HBaseAdmin#getTableNames(String)}}, which invokes {{HMaster#getTableNames}}. This implementation has different system table filtering logic from {{HMaster#getTableDescriptors}}. The latter is the call underlying the REST implementation.
