[jira] [Created] (HBASE-24549) Cluster locked up due to REST gateway queries for non-existent tables

Nick Dimiduk created HBASE-24549:
------------------------------------

             Summary: Cluster locked up due to REST gateway queries for non-existent tables
                 Key: HBASE-24549
                 URL: https://issues.apache.org/jira/browse/HBASE-24549
             Project: HBase
          Issue Type: Bug
          Components: REST
            Reporter: Nick Dimiduk


We had a case where a REST gateway instance was picked up by an automated security scanning tool. Many of the http requests it generated were interpreted requests against non-existent tables. The result was a flood of queries against meta, completely overrunning the priority queue of the region server hosting meta.

We need some kind of back pressure mechanism that can protect meta from a single bad actor.
