> [HBCK2] Regenerate missing table descriptors by hbck2
> -----------------------------------------------------
>
> Key: HBASE-25297
> URL: https://issues.apache.org/jira/browse/HBASE-25297
> Project: HBase
> Issue Type: Improvement
> Components: hbase-operator-tools, hbck2
> Affects Versions: hbase-operator-tools-1.0.0
> Reporter: Mate Szalay-Beko
> Assignee: Mate Szalay-Beko
> Priority: Major
> Fix For: hbase-operator-tools-1.1.0
>
>
> We just have been in a situation, when we saw many ServerCrashProcedure to be
> blocked, because of the AssignProcedure is blocked because of the missing
> .tabledesc files.
> {code:java}
> java.io.IOException: Missing table descriptor for
> dd0676f57bdbff5d04ab735b7daf5e9b
> {code}
>
> In our case it was OK for us to get rid of these tables and we were able to
> use {{setRegionState}} to move all these regions to {{FAILED_OPEN}} state,
> then disable and drop the tables. But this took a lot of time and we might
> not always have the option to drop these tables.
> HBCK 1 had a functionality (\{{fixTableOrphans}}) to regenerate the table
> descriptors "according to the memory cache or hdfs table directory
> structure". We should investigate if we can implement something like this
> with hbck2. We might not always be able to reproduce the table
> configurations, but we can probably make a "basic" one.
