Hudson commented on HBASE-5129: ------------------------------- Integrated in HBase-TRUNK #2621 (See [https://builds.apache.org/job/HBase-TRUNK/2621/]) hbase-5129 [BOOK] configuration.xml - changed the major compaction disable instruction from Long.MAX_VALUE to 0. > book is inconsistent regarding disabling - major compaction > ----------------------------------------------------------- > > Key: HBASE-5129 > URL: https://issues.apache.org/jira/browse/HBASE-5129 > Project: HBase > Issue Type: Bug > Components: documentation > Affects Versions: 0.90.1 > Reporter: Mikael Sitruk > Assignee: Doug Meil > Priority: Minor > Attachments: configuration_HBASE_5129.xml.patch > > > It seems that the book has some inconsistencies regarding the way to disable > major compactions > According to the book in chapter 2.6.1.1. HBase Default Configuration > hbase.hregion.majorcompaction - The time (in miliseconds) between 'major' > compactions of all HStoreFiles in a region. Default: 1 day. Set to 0 to > disable automated major compactions. > Default: 86400000 > (http://hbase.apache.org/book.html#hbase_default_configurations) > According to the book at chapter 2.8.2.8. Managed Compactions > "A common administrative technique is to manage major compactions manually, > rather than letting HBase do it. By default, > HConstants.MAJOR_COMPACTION_PERIOD is one day and major compactions may kick > in when you least desire it - especially on a busy system. To "turn off" > automatic major compactions set the value to Long.MAX_VALUE." > According to the code org.apache.hadoop.hbase.regionserver.Store.java, "0" is > the right answer. > (affect all documentation from 0.90.1) -- This message is automatically generated by JIRA.
