Let me change it to int. But 64 MB should be good enough because default
block size is 64 MB in Apache hadoop. In Cloudera hadoop is changed 128MB. But,
this allocation needs to be done in Java and hence restricting to less value
than 64 MB would put less burden on the java objects space management in
Trafodion.
