It is not always possible to > proportionally ingest data into DataNodes based on their remaining storage > capacity. Therefore it's possible for a subset of DataNodes to be much closer > to full capacity than the rest. > This heterogeneity is most likely rack-by-rack -- i.e. _m_ whole racks of > low-storage nodes and _n_ whole racks of high-storage nodes. So It'd be very > useful if we can lower the chance for those near-full DataNodes to become > destinations for the 2nd and 3rd replicas. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
