Heng Chen updated HBASE-14265:
------------------------------
Status: Patch Available (was: Open)
> we should forbidden create table using 'hbase' namespace
> --------------------------------------------------------
>
> Key: HBASE-14265
> URL: https://issues.apache.org/jira/browse/HBASE-14265
> Project: HBase
> Issue Type: Bug
> Reporter: Heng Chen
> Attachments: HBASE-14265.patch
>
>
> Now, there is no limit for users who can create table under 'hbase'
> NameSpace. I think it has some risk.
> Because we use {{TableName.systemTable}} to decide whether this table is
> System or not.
> But as code, {{TableName.systemTable}} will be true, if NS equals "hbase'
> {code}
> if (Bytes.equals(NamespaceDescriptor.SYSTEM_NAMESPACE_NAME, namespace)) {
> this.namespace = NamespaceDescriptor.SYSTEM_NAMESPACE_NAME;
> this.namespaceAsString =
> NamespaceDescriptor.SYSTEM_NAMESPACE_NAME_STR;
> this.systemTable = true;
> }
> {code}
>
> And we treat system table and normal table differently.
> For example, https://issues.apache.org/jira/browse/HBASE-14257 will flush
> fast if table belong to system table.
