Esteban Gutierrez commented on HBASE-22947:
-------------------------------------------
[~belugabehr], can you please elaborate more on this feature? We strictly
disallow to disable the {{hbase:meta}} table:
org.apache.hadoop.hbase.master.procedure.DisableTableProcedure#prepareDisable:
{code}
private boolean prepareDisable(final MasterProcedureEnv env) throws
IOException {
boolean canTableBeDisabled = true;
if (tableName.equals(TableName.META_TABLE_NAME)) {
setFailure("master-disable-table", new ConstraintException("Cannot
disable catalog table"));
canTableBeDisabled = false;
{code}
Probably we should add {{hbase:namespace}} there too.
