-------------------------------------
Summary: [pv2] Add display options/queries/info-display-design to
'Procedures & Locks' UI tab
Key: HBASE-23249
URL: https://issues.apache.org/jira/browse/HBASE-23249
Project: HBase
Issue Type: Sub-task
Components: UI
Reporter: Michael Stack
The 'Procedure & Locks' page in the Master UI lists all outstanding locks on
servers and regions, notes the current set of WAL files, and used-to list all
currently in-flight Procedures, even those that had completed successfully.
Debugging problems in assign and cluster dynamics, this page lists currently
problematic regions and their current state so is an import tool figuring where
to make repair. The parent issue removed the listing of procedures whose status
is SUCCESS for succesful completion because on any decent sized cluster, the
number of SUCCESS procedures were such that it was hard to find the
problematics.
This issue is about enhancing the 'P & L' page so if wanted, could list SUCCESS
procedures again with perhaps a filter mechanism to exclude if needed or to
filter on specific type; e.g. list all sub-procedures of procedure XYZ, and so
on. Really nice would be seeing in the UI a history of all transitions made by
a procedure; currently operator needs to grep logs.
