Subject Re: Hbase export / import Why doubling the Table Size ?

Hmm... I'm afraid I am out of options. If you want you can try to copy the table
from CHD3u2 and your CDH3B4 system, and see if the size remains doubled.

Does this happen with very small table, too? If so, you could take a small sample
HFile and upload it (both the CHD3B4 and CDH3u2 versions) somewhere so that we can have a
look.
