Kai Zheng updated HDFS-7337:
----------------------------
Description:
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.
