Ted Yu commented on HBASE-6205: ------------------------------- bq. prompt user if he/she is creating a table with the same name as one of the tables in trash I think the above is needed, especially if the table being created has different schema from the deleted table (which had the same name). > Support an option to keep data of dropped table for some time > ------------------------------------------------------------- > > Key: HBASE-6205 > URL: https://issues.apache.org/jira/browse/HBASE-6205 > Project: HBase > Issue Type: New Feature > Affects Versions: 0.94.0, 0.96.0 > Reporter: chunhui shen > Assignee: chunhui shen > Fix For: 0.96.0 > > Attachments: HBASE-6205.patch, HBASE-6205v2.patch, HBASE-6205v3.patch > > > User may drop table accidentally because of error code or other uncertain > reasons. > Unfortunately, it happens in our environment because one user make a mistake > between production cluster and testing cluster. > So, I just give a suggestion, do we need to support an option to keep data of > dropped table for some time, e.g. 1 day > In the patch: > We make a new dir named .trashtables in the rood dir. > In the DeleteTableHandler, we move files in dropped table's dir to trash > table dir instead of deleting them directly. > And Create new class TrashCleaner which will clean dropped tables if it is > time out with a period check. > Default keep time for dropped tables is 1 day, and check period is 1 hour. -- This message is automatically generated by JIRA.
