Kudu deployment best practice

[#1]

Hello!

We are going to use Kudu in our research platform, so there are several open questions. Could you share with us your experience in solving problems described below?

1) Best practice in Kudu deployment:
it is planned to use Kudu in conjunction with HDFS, so how do you usually solve the problem of sharing and flexible resource management between Kudu and HDFS?

2) Mixed workload processing (OLAP & OLTP):
in the case of mixed type of load has anybody faced with the problem of performance decrease? (slowdown of disk I/O and etc)

We have 20 nodes in cluster. Each node has 10 x 8 TB 7,200 RPM High Capacity SAS Drives for data storage (HDFS now) and 2x SSD for OS.

Thank in advance!
