Accumulo will balance the tablets based on the configured balancer. Without getting down into the details, the splits will be moved to other nodes.
The Details: It depends. With the default balancer, it will try to smooth out the number of tablets among servers, by table. So, if this table goes from 1 tablet to 3, and there are at least 3 servers, each split will eventually find itself moved to separate server. But, if you add one split among hundreds, it may not make much of a difference to bother moving the tablet. -Eric On Tue, Oct 20, 2015 at 10:39 AM, z11373 <z11...@outlook.com> wrote: > As my understanding, Accumulo will have data already sorted with row id, > and > if the number of rows is growing, it will split the tablet at one point. > For example, let say I have following row ids: > > 1_abcxxx > 1_abdxxx > 1_abexxx > 1_abfxxx > 1_abgxxx > 1_abhxxx > 1_abixxx > ... > 1_zzzxxx > 2_abcxxx > 2_abdxxx > 2_abexxx > 2_abfxxx > 2_abgxxx > 2_abhxxx > ... > > Let say the data with row id starts with "1_" has a million of rows, and > for > sake of example, let say the tablet size is 400K, so in this case the "1_" > data will be split into 3 tablets. > > My question is will Accumulo distribute those 3 tablets into different > tablet server nodes?
