[jira] [Created] (ACCUMULO-367) distribute the master function via
iterators, including consistency checks
distribute the master function via iterators, including consistency checks
--------------------------------------------------------------------------
Key: ACCUMULO-367
URL: https://issues.apache.org/jira/browse/ACCUMULO-367
Project: Accumulo
Issue Type: Improvement
Components: master, tserver
Reporter: Eric Newton
Assignee: Eric Newton
Fix For: 1.5.0
ACCUMULO-315 and ACCUMULO-365 are a result of inconsistent reads of the metadata table. If we moved more of the !METADATA scan work to the tablet servers, and had them verify the consistency as they read, the main loop of the master would not have to manage consistency with secondary scans. We could even restructure the main loop to execute in a distributed fashion on the tablet servers.
