Hi,   We are analyzing kudu for production in real time ingestion but we are not sure about how much disk/ram needs, I have understood that kudu storage does not work with hdfs means that we need additional resources and we don´t know how much disk/ram for each 1gb of data ingested storaged from kafka.   how can I control cuota (%) for each process if kudu does not work with YARN? Do you recomend separated cluster for kudu to control memory usage?  Are there any formula to calculate additional hardware for kudu? disk=replication factor * data? and memory? If kudu does not need HDFS for storage probably HDFS is not necessary. Isn´t that right?   Thanks in advance ... View more

I am using Impala+kudu table, I don´t know if Impala is just a interface to see that tables in hue/shell or it works as proces engine when I launch a query (select,update). ¿Is it using Impala when I launch a query? Impala+kudu allows UDF or it just works for Impala (without kudu storage) ?   thanks in advance ... View more
