Configure and Start Apache HBase
The hbase.bucketcache.percentage.in.combinedcache is removed in HDP-2.5.0. This simplifies the configuration of block cache. BucketCache configurations from HDP 2.1 need to be recalculated to attain identical memory allotments in HDP-2.5.0. The L1 LruBlockCache is whatever hfile.block.cache.size is set to and the L2 BucketCache is whatever hbase.bucketcache.size is set to.
Upgrade Apache HBase.
hbase upgrade -executeReplace your configuration after upgrading. Replace the HBase template configuration in
/etc/hbase/conf.Start services. From root, assuming that $HBASE_USER=hbase:
su - hbase -c "/usr/hdp/current/hbase-master/bin/hbase-daemon.sh start master; sleep 25"su - hbase -c "/usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh start regionserver"Check processes.
