LA-HUG HBASE DO’s and DON’Ts from Shopzilla on Vimeo.

At glance, the dos and don’ts are:

Do:

• Use a key prefix that distributes well
• Keep the number of regions reasonable – about 100 per node.
• Disable auto-compaction
• Use compression
• Explicitly put hbase-site.xml in your CLASSPATH
• Monitor the health of your cluster
• Store multiple copies for different access patterns

Don’t:

• Wholesale replacement of every RDBMS
• Run huge MR Jobs directly off of HBase
• Use timestamps as teh first part of your key
• Allocate all CPUs to your TaskTrackers
• Mixed workloads with SLAs
• Use a single client bulk load or bulk load with put
• Let the Region Server Swap
