Here are the Requirements:
Suppose you were given the following. How would you begin configuring Hortonworks for Hive? Would you focus on storage? How can we configure for compute?
So where do we begin?
First Some Quick Calculations:
Memory per Core: 122GB/16 = 7.625; Approximate 8 GB per CPU Core
This means our largest Container Size PER Node per core is 8 GB
However we should not reserve all 16 Cores to Hadoop. Some Cores are need for OS and other processes.
Let's Assume 14 Cores is reserved for YARN.
Memory Allocated for All YARN containers on a node = No. of Virtual Cores x Memory Per Core
114688 MB = 14 * 8192 MB (8 *1024)
