Configure and Start Apache HBase
The hbase.bucketcache.percentage.in.combinedcache is removed in HDP-2.3.4.7. This simplifies the configuration of block cache. BucketCache configurations from HDP 2.1 will need to be recalculated to attain identical memory allotments in HDP-2.3.4.7. The L1 LruBlockCache will be whatever hfile.block.cache.size is set to and the L2 BucketCache will be 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:
