---------------------------------
Summary: improve visibility into the bootstrapping status of a
tablet server
Key: KUDU-3138
URL: https://issues.apache.org/jira/browse/KUDU-3138
Project: Kudu
Issue Type: Improvement
Components: ksck, server, supportability, ui
Reporter: Andrew Wong
Today, the best way to understand the happenings of a tserver startup is to
look at the {{/tablets}} page in the tserver's web UI and watch the number of
{{RUNNING}} tablets gradually but hopefully increase.
It might be helpful to know about some other things, like:
- progress in initializing the block manager
- what tablets are currently being bootstrapped
- the size of the WALs for tablets that need bootstrapping, since this may
indicate how much work there is to bootstrap
- the number of rowsets contained by the tablets that need bootstrapping,
since this may indicate how much work there is to bootstrap
Also, in a similar way that we label recovering tservers as "recovering", we
may want to consider softer language like "initializing" or "bootstrapping" for
tablets that have any replicas in the {{INITIALIZING}} state.
