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. -- Lars ----- Original Message ----- From: Lord Khan Han <[email protected]> To: [email protected]; lars hofhansl <[email protected]> Cc: Sent: Friday, December 9, 2011 2:45 PM Subject: Re: Hbase export / import Why doubling the Table Size ? in same configured cluster (carbon copy) when I made import there is no increas on size.. same size.. problem in the cdh3u2..
