[jira] [Created] (HBASE-28034) Rewrite hbck2 documentation using ChatGPT
Nihal Jain created HBASE-28034: -- Summary: Rewrite hbck2 documentation using ChatGPT Key: HBASE-28034 URL: https://issues.apache.org/jira/browse/HBASE-28034 Project: HBase Issue Type: Improvement Reporter: Nihal Jain Assignee: Nihal Jain Just a thought, could we re-write the operator tools [README.md|https://github.com/apache/hbase-operator-tools/blob/master/README.md] using ChatGPT and make it better? A sample paragraph re-written by ChatGPT is as follows: Original: {quote} h3. Some General Principals When making repair, make sure hbase:meta is consistent first before you go about fixing any other issue type such as a filesystem deviance. Deviance in the filesystem or problems with assign should be addressed after the hbase:meta has been put in order. If hbase:meta is out of whack, the Master cannot make proper placements when adopting orphan filesystem data or making region assignments. Other general principles to keep in mind include a Region can not be assigned if it is in _CLOSING_ state (or the inverse, unassigned if in _OPENING_ state) without first transitioning via {_}CLOSED{_}: Regions must always move from {_}CLOSED{_}, to {_}OPENING{_}, to {_}OPEN{_}, and then to {_}CLOSING{_}, {_}CLOSED{_}. When making repair, do fixup of a table-at-a-time. Also, if a table is {_}DISABLED{_}, you cannot assign a Region. In the Master logs, you will see that the Master will report that the assign has been skipped because the table is {_}DISABLED{_}. You may want to assign a Region because it is currently in the _OPENING_ state and you want it in the _CLOSED_ state so it agrees with the table's _DISABLED_ state. In this situation, you may have to temporarily set the table status to {_}ENABLED{_}, just so you can do the assign, and then set it back again after the unassign. _HBCK2_ has facility to allow you do this. See the _HBCK2_ usage output. What follows is a mix of notes and prescription that comes of experience running hbase-2.x so far. The root issues that brought on states described below has been fixed in later versions of hbase so upgrade if you can so as to avoid scenarios described. {quote} Rephrased: {quote}*Some Basic Principles* Ensure hbase:meta's consistency before attempting to fix any other type of problem, such as filesystem deviations. Issues related to filesystem or assignment should be addressed once hbase:meta is sorted out. If hbase:meta is awry, the Master cannot accurately allocate orphan filesystem data or region assignments.
