Ted Yu commented on HBASE-18083: -------------------------------- Should be fine. > Make large/small file clean thread number configurable in HFileCleaner > ---------------------------------------------------------------------- > > Key: HBASE-18083 > URL: https://issues.apache.org/jira/browse/HBASE-18083 > Project: HBase > Issue Type: Bug > Reporter: Yu Li > Assignee: Yu Li > Fix For: 3.0.0 > > Attachments: HBASE-18083.patch, HBASE-18083.v2.patch, > HBASE-18083.v3.patch > > > Currently we have only one thread for both large and small file cleaning, but > when write pressure is huge we might need more cleaner threads, so we need to > make the thread number configurable. > We observed more than 1.8PB data in archive directory online due to business > access rate change, and this proposal is one of the necessary changes > required. > Default value of the configurations would still be left to 1 to keep low > pressure to NN for normal case. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
