Kai Zheng commented on HDFS-7859: --------------------------------- I remembered what we have confirmed is for phase-1 we have some built-in policies, like the default one 6+3-64k? I suggest we add another one using 10+4-64k to exercise the codes supporting multiple policies. Sounds good to me to do the work adding or removing policies in addition to this. > Erasure Coding: Persist erasure coding policies in NameNode > ----------------------------------------------------------- > > Key: HDFS-7859 > URL: https://issues.apache.org/jira/browse/HDFS-7859 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Xinwei Qin > Labels: BB2015-05-TBR, hdfs-ec-3.0-must-do > Attachments: HDFS-7859-HDFS-7285.002.patch, > HDFS-7859-HDFS-7285.002.patch, HDFS-7859-HDFS-7285.003.patch, > HDFS-7859.001.patch, HDFS-7859.002.patch, HDFS-7859.004.patch, > HDFS-7859.005.patch > > > In meetup discussion with [~zhz] and [~jingzhao], it's suggested that we > persist EC schemas in NameNode centrally and reliably, so that EC zones can > reference them by name efficiently. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
