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-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
