Data Placement Strategy for HDFS

Hi,

I want to customize the data placement strategy rather than using the default strategy in HDFS. Is there any way to control which datanode the replica is delivered to?

Thank you in advance.

Best regards,
Fei

Re: Data Placement Strategy for HDFS

Posted by Fei Hu <hu...@gmail.com>.
Hi,

Thank you for your help.

I searched HDFS-7613 by Google and the link https://issues.apache.org/jira/issues/?jql=project%20%3D%20HDFS%20AND%20text%20~%20%227613%22 <https://issues.apache.org/jira/issues/?jql=project%20=%20HDFS%20AND%20text%20~%20%227613%22>, but I could not find it.

Could you email me the link? Thank you very much.

Sincerely,
Fei

Thank you for your quick response.

After reading the materials you recommended, my conclusion is that Hadoop
does not provide interface to customize the data placement policy. We need
to add some codes to the source package of HDFS. Is that right?

Thanks,
Fei
