Todd Lipcon commented on KUDU-1597:
-----------------------------------
Does it seem reasonable to just add a call to tablet_peer_->CheckRunning() in
the SysCatalogTable::Visit*() functions? If that sounds right I'll take a whack
at this.
> 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.
