Kai Zheng commented on HADOOP-13665: ------------------------------------ Thanks [~kaisasak]! I guess we're much aligned. We don't need {{io.erasurecode.codec.rs.rawcoder}} any more if we have {{io.erasurecode.codec.rs.rawcoders}}. I mean, if the value of {{...rawcoders}} contains more than one, we use the first one; if just one, it's OK and we just use it. Sounds good? > Erasure Coding codec should support fallback coder > -------------------------------------------------- > > Key: HADOOP-13665 > URL: https://issues.apache.org/jira/browse/HADOOP-13665 > Project: Hadoop Common > Issue Type: Sub-task > Components: io > Reporter: Wei-Chiu Chuang > Assignee: Kai Sasaki > Priority: Blocker > Labels: hdfs-ec-3.0-must-do > Attachments: HADOOP-13665.01.patch, HADOOP-13665.02.patch, > HADOOP-13665.03.patch, HADOOP-13665.04.patch, HADOOP-13665.05.patch > > > The current EC codec supports a single coder only (by default pure Java > implementation). If the native coder is specified but is unavailable, it > should fallback to pure Java implementation. > One possible solution is to follow the convention of existing Hadoop native > codec, such as transport encryption (see {{CryptoCodec.java}}). It supports > fallback by specifying two or multiple coders as the value of property, and > loads coders in order. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
