> 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 ....
