------------------------------------
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.
