./hbase pe --nomapred --rows=1 sequentialWrite 1
I inserted 1 row with 1 client
How to understand above result in hbase pe
what is 95%,99%,99.999%....
what is Summary of timings (ms): Min: 106ms Max: 106ms Avg: 106ms
what is relation between them
Anyone please help to solve this......
As I understand from here, with sequentialWrite one runs sequential write test. Here 99.99th and others are basically performance metrics for write. for example 99.99th is 99.99th percentile of all the write time taken, which you can understand here. As you have only inserted one row, all 95%,99%,99.999% numbers are same, but they will be different if you test by inserting many rows.
Same is case with Min, Max and Avg, as with only one test case, they are same. if there are 10 rows inserted, Avg will be average of time taken of all the rows.
