Configure and Start Apache HBase

The is removed in HDP-2.5.3. This simplifies the configuration of block cache. BucketCache configurations from HDP 2.1 need to be recalculated to attain identical memory allotments in HDP-2.5.3. The L1 LruBlockCache is whatever hfile.block.cache.size is set to and the L2 BucketCache is whatever hbase.bucketcache.size is set to.

  1. Upgrade Apache HBase.

    hbase upgrade -execute

  2. Replace your configuration after upgrading. Replace the HBase template configuration in /etc/hbase/conf.

  3. Start services. From root, assuming that $HBASE_USER=hbase:

    su - hbase -c "/usr/hdp/current/hbase-master/bin/ start master; sleep 25"

    su - hbase -c "/usr/hdp/current/hbase-regionserver/bin/ start regionserver"

  4. Check processes.

    ps -ef | grep -i hmaster

    ps -ef | grep -i hregion
