As we know Default Minimum Container Size is 1024 MBs
Consider Hadoop Cluster <1-Master & 3-Datanodes>
Namenode : master (3GB RAM, 2 Cores)
Datanodes : data1 (512MB RAM, 1 Core),
data2(512MB RAM, 1 Core),
data3(1GB RAM, 1 Core).
Input File Size : "File"=500MB with Replication factor 3 (All the nodes having all the blocks)
Default Block Size = 128 MB
therefor "File" will be split into 4-Blocks
Due to Repli.Factor = 3, all the nodes will be having all the 4-Blocks i.e 4-Containers.
Default Minimum Container Size is 1024 MBs
Question1 : On which datanode AM will allocate Container?
Question2 : Data1 & Data2 has 512MB of RAM, Does that mean AM will never allocate container on these datanodes???
