James Taylor updated PHOENIX-4214: ---------------------------------- Attachment: PHOENIX-4214-4.x-HBase-0.98_v1.patch [~vincentpoon] - this test is hanging on 0.98 (see attached). Please advise. > Scans which write should not block region split or close > -------------------------------------------------------- > > Key: PHOENIX-4214 > URL: https://issues.apache.org/jira/browse/PHOENIX-4214 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.12.0 > Reporter: Vincent Poon > Assignee: Vincent Poon > Attachments: PHOENIX-4214-4.x-HBase-0.98_v1.patch, > PHOENIX-4214.master.v1.patch, splitDuringUpsertSelect_wip.patch > > > PHOENIX-3111 introduced a scan reference counter which is checked during > region preSplit and preClose. However, a steady stream of UPSERT SELECT or > DELETE can keep the count above 0 indefinitely, preventing or greatly > delaying a region split or close. > We should try to avoid starvation of the split / close request, and > fail/reject queries where appropriate. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
