--------------------------------
Summary: Master crashes if web UI is visited during startup
Key: KUDU-1597
URL: https://issues.apache.org/jira/browse/KUDU-1597
Project: Kudu
Issue Type: Bug
Components: master
Affects Versions: 0.10.0
Reporter: Adar Dembo
Priority: Critical
Accessing certain paths in the master web UI during startup can cause the
master to crash. For example, /dump-entities while the master tablet is still
bootstrapping will lead to a CHECK crash (SysCatalogTable has an uninitialized
schema at this point). There are no doubt others too.
We haven't seen this in testing because our tests generally don't access the
web UI, or they don't try to bootstrap a large master tablet. We've seen at
least one user hit this, though: for some reason the master tablet was enormous
(i.e. it took at least a minute to bootstrap) and the Cloudera Manager agent
was periodically accessing /dump-entities.
