Kai Zheng updated HDFS-7337: ---------------------------- Attachment: PluggableErasureCodec.pdf For time saving, I composed this doc to illustrate the erasure codec framework for review. Your feedback is welcome. > Configurable and pluggable Erasure Codec and schema > --------------------------------------------------- > > Key: HDFS-7337 > URL: https://issues.apache.org/jira/browse/HDFS-7337 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Zhe Zhang > Assignee: Kai Zheng > Attachments: HDFS-7337-prototype-v1.patch, 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 (v6.3.4#6332)
