Vinod Kumar Vavilapalli commented on HDFS-11742: ------------------------------------------------ bq. If 2.8.1 is put up for vote with this, I will have to -1 the release. bq. It will affect many users, if it is included in a release as is. I will -1 the release if the issue is not properly addressed. I'm pushing for the next 2.8 maint release as well as 2.7.x. [~kihwal] / [~szetszwo], can you please help get ourselves to a convergence?

In > both cases, it would hang forever after two iterations. The two iterations > were also moving things at a significantly lower rate. The hang itself is > fixed by HDFS-11377, but the design limitation remains, so the balancer > throughput ends up actually lower. > Instead of reverting HDFS-8188 as originally suggested, I am making a small > change to make it less error prone and more usable. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
