-1 I have been experimenting with RC5 and running continuous ingest. I noticed it was not keeping much data in memory. When a tablet server had lots of tablets it was writing out really small files. I tracked down the cause of this, the walog max size is set to 100M. Also a tablet will compact after it has 3 walogs. In effect this limits the tablet server to 300M of memory even though its configured to use 1G.
The files in <acumulo>/conf/examples all set the walog to 100M. These config changes were made late in the game after a lot of testing was done. While these configs may be good for running accumulo on a laptop, none of them are good for running on a cluster w/ reasonable nodes. I want to see 1.4 released, but I also want user to have a good experience out of the box. That is why I am voting -1 on this. We should provide the config that we tested with as an example which is good for servers.
