Eungsop Yoo updated HBASE-15055: -------------------------------- Release Note: Do not skip large files when the sum of the size of TTL expired store files is greater than threshold. Major compaction should be triggered to delete TTL expired records. One parameter is added, "hbase.hstore.expired.size.ratio". When 0.0 is set to this parameter, major compaction is triggered if there is any TTL expired records. When 1.0 is set, all of large files are skipped regardless of the existence of TTL expired records. The default is 0.5, major compaction is triggered if above 50% of the store files in size have TTL expired records. > Major compaction is not triggered when both of TTL and > hbase.hstore.compaction.max.size are set > ----------------------------------------------------------------------------------------------- > > Key: HBASE-15055 > URL: https://issues.apache.org/jira/browse/HBASE-15055 > Project: HBase > Issue Type: Bug > Reporter: Eungsop Yoo > Assignee: Eungsop Yoo > Priority: Minor > Attachments: HBASE-15055-v1.patch, HBASE-15055-v2.patch, > HBASE-15055-v3.patch, HBASE-15055-v4.patch, HBASE-15055-v5.patch, > HBASE-15055.patch > > > Some large files may be skipped by hbase.hstore.compaction.max.size in > candidate selection. It causes skipping of major compaction. So the TTL > expired records are still remained in the disks and keep consuming disks. > To resolve this issue, I suggest that to skip large files only if there is no > TTL expired record. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
