[jira] [Created] (HBASE-14265) we should forbidden create table
using 'hbase' namespace
Heng Chen created HBASE-14265:
---------------------------------
Summary: 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
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.
