Rakesh R commented on HDFS-7337: -------------------------------- bq. Is there a jira for persisting EC policy to NN metadata? HDFS-7859, hope this jira will help you to get more info. > Configurable and pluggable erasure codec and policy > --------------------------------------------------- > > Key: HDFS-7337 > URL: https://issues.apache.org/jira/browse/HDFS-7337 > Project: Hadoop HDFS > Issue Type: New Feature > Components: erasure-coding > Reporter: Zhe Zhang > Assignee: SammiChen > Priority: Critical > Labels: hdfs-ec-3.0-nice-to-have > Fix For: 3.0.0-beta1 > > Attachments: HDFS-7337-prototype-v1.patch, > HDFS-7337-prototype-v2.zip, HDFS-7337-prototype-v3.zip, PluggableErasureCodec > v4.pdf, PluggableErasureCodec-v2.pdf, PluggableErasureCodec-v3.pdf, > PluggableErasureCodec.pdf > > > According to HDFS-7285 and the design, this considers to support multiple > Erasure Codecs via pluggable approach. It allows to define and configure > multiple codec schemas with different coding algorithms and parameters. The > resultant codec schemas can be utilized and specified via command tool for > different file folders. While design and implement such pluggable framework, > it’s also to implement a concrete codec by default (Reed Solomon) to prove > the framework is useful and workable. Separate JIRA could be opened for the > RS codec implementation. > Note HDFS-7353 will focus on the very low level codec API and implementation > to make concrete vendor libraries transparent to the upper layer. This JIRA > focuses on high level stuffs that interact with configuration, schema and etc. -- 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
