-----------------------------------
Good points.
I think the very first step is to draft a wiki to introduce all the useful
utility tools.
> Add execution of "utility" classes to the System tab of Kylin UI
> ----------------------------------------------------------------
>
> Key: KYLIN-1829
> URL: https://issues.apache.org/jira/browse/KYLIN-1829
> Project: Kylin
> Issue Type: Improvement
> Reporter: Richard Calaba
>
> There is a bunch of "hidden" and/or semi-documented classes in Kylin engine
> which can be very useful for standard maintenance of healthy Kylin instance -
> it would be very good if those are connected to the System tab of the Kylin
> UI so administrators can run them directly from Kylin UI and collect their
> execution log also there, few candidates:
> 1) ./bin/kylin.sh org.apache.kylin.storage.hbase.util.StorageCleanupJob
> 2) ./bin/kylin.sh org.apache.kylin.cube.cli.CubeSignatureRefresher
> 3) ./bin/metastore.sh for backup/restore actions with support to list the
> content of ./meta_backups directory
> In addition I found many Kylin engine classes with main method (thus
> executable tools for Kylin) which might be also good candidates to be
> integrated here - just do not know their functions/parameters. To know I
> would have to read the code of all of them. Maybe the authors of the tools
> can create official list with documentation of supported parameters - and
> this list/docu can be also part of the System tab on UI.
> Few other classes I found - executable through kylin.sh - some of those
> probably already connected to UI in 1.5.2.1 (like the diagnostics CLI ..)
> But some of those I still do not know what they are for .. though the classes
> having CLI in the name give impression that those should be "stable" internal
> interfaces for Kylin engine.
> ./bin/kylin.sh org.apache.kylin.tool.CubeMetaExtractor
> ./bin/kylin.sh org.apache.kylin.tool.DiagnosisInfoCLI
> ./bin/kylin.sh org.apache.kylin.tool.HBaseUsageExtractor
> ./bin/kylin.sh org.apache.kylin.tool.JobDiagnosisInfoCLI
> ./bin/kylin.sh org.apache.kylin.job.hadoop.invertedindex.IICLI - error
> ./bin/kylin.sh org.apache.kylin.common.KylinVersion - this would be good to
> have on UI for sure -> sometimes I do need to know exact Kylin version
> ./bin/kylin.sh org.apache.kylin.common.persistence.ResourceTool - this is
> basically metastore.sh
> ./bin/kylin.sh org.apache.kylin.cube.cli.DumpDictionaryCLI
> ./kylin.sh org.apache.kylin.cube.cuboid.CuboidCLI
> ./kylin.sh org.apache.kylin.query.QueryCli
> ... and some others ....
