stack updated HBASE-17097: -------------------------- Fix Version/s: (was: 2.0.0) > Documentation for max off heap configuration > -------------------------------------------- > > Key: HBASE-17097 > URL: https://issues.apache.org/jira/browse/HBASE-17097 > Project: HBase > Issue Type: Sub-task > Components: documentation > Affects Versions: 2.0.0 > Reporter: Anoop Sam John > Priority: Major > > {quote} > \# Uncomment below if you intend to use off heap cache. For example, to > allocate 8G of > \# offheap, set the value to "8G". > \# export HBASE_OFFHEAPSIZE=1G > {quote} > This is what we have in hbase-env.sh now. We need more notes around this and > some suggestion. May be more details in book also. This depends on whether we > want L2 off heap BC as the default data cache in 2.0. (I would like to and > will open a jira soon) Also if users use off heap MSLAB pool, then that also > to be added up.. > As of now we will use a ByteBufferPool which pool direct BBs and this is ON > by default. The max size, this pool can keep is 2 MB * 2 * #handlers. > Will add more details as we turn ON other features. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
