FAQ
config parameter hbase.io.index.interval should be hbase.index.interval, accroding to HBaseMapFile.HbaseWriter
---------------------------------------------------------------------------------------------------------------

Key: HBASE-680
URL: https://issues.apache.org/jira/browse/HBASE-680
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.1.2
Environment: it's a mistack in source code or default configuration fail.
Reporter: LN


in conf/hbase-default.xml and FAQ, there has a performance tuning parameter "hbase.io.index.interval", but can't find any usage in sources. instead, HStoreFile.java #585 using "hbase.index.interval" to set mapfile index interval (setIndexInterval). so i think HStoreFile.java mistyped the parameter name.

    LN updated HBASE-680:
    ---------------------

    Component/s: regionserver
    Priority: Minor (was: Major)
    Description:
    in conf/hbase-default.xml and FAQ, there has a performance tuning parameter "hbase.io.index.interval", but can't find any usage in sources. instead, HStoreFile.java #585 using "hbase.index.interval" to set mapfile index interval (setIndexInterval). so i think HStoreFile.java mistyped the parameter name.

    this mistake will make users thinkgs "hbase.io.index.interval" useless.
