> 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.
