[jira] [Reopened] (ACCUMULO-1421) use reflection to improve
compatibility between Hadoop 1 and 2 JobContext objects
[ https://issues.apache.org/jira/browse/ACCUMULO-1421?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adam Fuchs reopened ACCUMULO-1421:
----------------------------------
Mike Berman found another issue: org.apache.hadoop.net.NetUtils.getInputStream(Ljava/net/Socket;J)Ljava/io/InputStream; became org.apache.hadoop.net.NetUtils.getInputStream(Ljava/net/Socket;J)Lorg/apache/hadoop/net/SocketInputWrapper;. We use this at org.apache.accumulo.core.util.TTimeoutTransport.create(TTimeoutTransport.java:39). This breaks bytecode compatibility, but not source code compatibility. Time for more reflection!

> JobContext switches between an abstract class and an interface in hadoop 1 and 2, causing runtime compatibility problems in the compiled Accumulo bytecode. Avoid the runtime problem by using reflection to access the configuration object stored in the JobContext.
