> Safer table creation and deletion using .tmp dir
> ------------------------------------------------
>
> Key: HBASE-7365
> URL: https://issues.apache.org/jira/browse/HBASE-7365
> Project: HBase
> Issue Type: Improvement
> Components: master
> Reporter: Matteo Bertozzi
> Assignee: Matteo Bertozzi
> Fix For: 0.96.0
>
> Attachments: HBASE-7365-v0.patch, HBASE-7365-v1.patch,
> HBASE-7365-v2.patch
>
>
> Currently tables are created in the root directory, and the removal works on
> the root directory.
> Change the code to use a /hbase/.tmp directory to make the creation and
> removal a bit safer
> Table Creation steps
> * Create the table descriptor (table folder, in /hbase/.tmp/)
> * Create the table regions (always in temp)
> * Move the table from temp to the root folder
> * Add the regions to meta
> * Trigger assignment
> * Set enable flag in ZooKeeper
> Table Deletion steps
> * Wait for regions in transition
> * Remove regions from meta (use bulk delete)
> * Move the table in /hbase/.tmp
> * Remove the table from the descriptor cache
> * Remove table from zookeeper
> * Archive the table
> The main changes in the current code are:
> * Writing to /hbase/.tmp and then rename
> * using bulk delete in DeletionTableHandler
