最近體驗了一下 kudu 1.8 的 Rebalance 功能，感覺很不錯。感覺特別不爽的是編譯安裝之後程序的體量之大，實乃聞所未聞，達到可怕的 46GB。各位小夥伴們安裝前要有心裏準備。

Rebalance測試
如果想測試 rebalance，可以先配置 3 個 tserver 節點，多建幾張表；再添加 1 個或 2 個 tserver 節點，執行以下 rebalance 命令進行數據均衡：
kudu cluster rebalance kudu:7050,kudu:7051,kudu:7052
執行以下命令對指定表進行數據均衡：
kudu cluster rebalance --tables test,test1 kudu:7050,kudu:7051,kudu:7052
