So its saying my heap size is  (Heap Size is 27.25 MB/888.94 MB)
but my configured capacity is 971GB (4 nodes)

 

Is heap size on the main page just for the namenode or do I need to
increase it to include the datanodes

 

Cheers -

The 'heap size' is a Java/program and memory (RAM) thing; unrelated to
physical disk space that the HDFS may occupy (which can be seen in
configured capacity).

Its related with the amount of memory available to Java Virtual machine that
is created for hadoop jobs.
