Hi,
*I want to upgrade our hbase cluster from version 0.20.6 to 0.92, but the hbase book just tell me how to upgrade from version 0.90 to 0.92.* *So I have a doubt that: * *Can I directly upgrade? Or I have to firstly upgrade it to 0.90 version, then upgrade it from verion 0.90 to 0.92.* * * *And 0.20.6 to 0.90, just replace the jar file and run:* *hbase org.jruby.Main $HBASE_HOME/bin/set_meta_memstore_size.rb* * * *And 0.90 to 0.92, just change the zookeeper version to 3.4.2 and take care the below confs:* *-- base.hregion.memstore.mslab.enabled* *-- adds distributed WAL log splitting in place of single-process master orchestrated splitting(default on)* *-- hbase.instant.schema.alter.enabled* *-- off-heap cache* *-- regionserver OOM kill -9* * * *Does there have steps that I omit?* * * *Thanks,* *Jameson Li.*
