Default split policy for 0.94.17 is IncreasingToUpperBoundRegionSplitPolicy. Since you did not set a specific policy in your config file, that's the one used.
Comments from the class: * Split size is the number of regions that are on this server that all are * of the same table, cubed, times 2x the region flush size OR the maximum * region split size, whichever is smaller. For example, if the flush size * is 128M, then after two flushes (256MB) we will split which will make two regions * that will split when their size is 2^3 * 128M*2 = 2048M. If one of these * regions splits, then there are three regions and now the split size is * 3^3 * 128M*2 = 6912M, and so on until we reach the configured * maximum filesize and then from there on out, we'll use that.
