+ Upgrading <code>META</code> to use Protocol Buffers (Protobuf) + When you upgrade from 0.96.x to 0.98.x, META needs to be converted to use protocol + buffers. This is controlled by the configuration option + , which is set to + true by default. Therefore, by default, no action is required + on your part. + After the migration is complete, if your META is very large, you may + notice that scanning of META takes a long time at start-up. If this is + the case, and you know that your META has already been converted, you + can set to false in + hbase-site.xml. This should be considered an expert-level + and very experimental setting. +
