Subject [jira] [Updated] (HBASE-12569) Control MaxDirectMemorySize in the same manner as heap size
Date Tue, 25 Nov 2014 17:22:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12569?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Elliott Clark updated HBASE-12569:
----------------------------------
    Release Note: Adds new JAVA_OFFHEAP_MAX environment variable to ./bin/hbase. Set the max
offheap memory java will request with this one variable.  It combines with JAVA_HEAP_MAX as
follows HEAP_SETTINGS="$JAVA_HEAP_MAX $JAVA_OFFHEAP_MAX"  (was: Adds new HEAP_SETTINGS environment
variable to ./bin/hbase. Set java on and offheap with this one variable.  It equates as follows
HEAP_SETTINGS="$JAVA_HEAP_MAX $JAVA_OFFHEAP_MAX")

> Control MaxDirectMemorySize in the same manner as heap size
> -----------------------------------------------------------

> It would make it much easier on us if we could manage MaxDirectMemorySize in the same
way as heap. This patch allows that to happen.
> Note: I have not tested the *.cmd modifications as I don't have a Windows box (at the
moment, can test at home) but look like they should work (famous last words).
