[jira] Created: (HBASE-999) Up versions on historian and keep
history of deleted regions for a while rather than delete immediately
Up versions on historian and keep history of deleted regions for a while rather than delete immediately
-------------------------------------------------------------------------------------------------------
Key: HBASE-999
URL: https://issues.apache.org/jira/browse/HBASE-999
Project: Hadoop HBase
Issue Type: Improvement
Reporter: stack
Fix For: 0.19.0
Since removal of master logging of all rows of catalog tables, there is a hole when it comes to debugging what happened in hbase at some time in the past. The region historian is the place we keep up region history only we've been deleting old history when region is deleted. Instead, lets not delete region history but keep it around a while, say a week. Also, keep all versions -- currently its set to 1.
To do this, may need to also so HBASE-998.

[jira] Updated: (HBASE-999) Up versions on historian and keep

stack updated HBASE-999:
------------------------
Attachment: historian.patch
Change delete of a region so it doesn't remove historian content. Change historian column family so it times out after a week rather than lives for ever.
Now, if you select on catalog tables, will probably need to narrow select to info: else get loads of historian noise you'll not usually be interested in.

Make it so parent region in historian split messages is clickable. Clicking it takes you to the region historian of the parent, and so on back in time.
