It allows to define and configure m= ultiple 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=E2=80=99s also to implement a concrete codec by default (Reed Solomon)= to prove the framework is useful and workable. Separate JIRA could be open= ed for the RS codec implementation. > Note HDFS-7353 will focus on the very low level codec API and implementat= ion 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-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
