Andrew Wang updated HDFS-7345: ------------------------------ Component/s: erasure-coding > Local Repairable Codes (LRC) > ---------------------------- > > Key: HDFS-7345 > URL: https://issues.apache.org/jira/browse/HDFS-7345 > Project: Hadoop HDFS > Issue Type: New Feature > Components: erasure-coding > Reporter: Kai Zheng > Assignee: Yi Liu > Attachments: LRC-compare.pdf > > > HDFS-7285 proposes to support Erasure Coding inside HDFS, supports multiple > Erasure Coding codecs via pluggable codec framework (HDFS-7337) and > implements Reed Solomon code by default. This is to support a more advanced > coding mechanism, Local Repairable Codes (LRC). As discussed in [Xorbas > Hadoop Project Page|http://smahesh.com/HadoopUSC/] and the paper attached > there, LRC can reduce the number of erasure coding chunks that need to be > read when recovering missing data chunks, while still keeping the storage > overhead low. -- 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
