But I think I have seen 6+3 as well somewhere. In both cases you should be able to roughly count with 50% overhead. But as Neeraj says we will have to wait to see final figures.</P><P><A href="https://issues.apache.org/jira/browse/HDFS-7285" target="_blank">https://issues.apache.org/jira/browse/HDFS-7285</A></P> Thu, 18 Feb 2016 06:57:49 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/How-to-calculate-space-quota-for-erasure-coded-directory/m-p/146073#M19960 bleonhardi 2016-02-18T06:57:49Z Re: How to calculate space quota for erasure coded directory? https://community.cloudera.com/t5/Archives-of-Support-Questions/How-to-calculate-space-quota-for-erasure-coded-directory/m-p/146074#M19961 <P>6+3 worked for me.
