To reply, visit: https://reviews.apache.org/r/963/ ----------------------------------------------------------- Review request for hbase. Summary ------- There is no test case for testing coprocesors class loading from hdfs or local file system. Add test cases for cp class loading. It does: - compile a cp implementation on the fly by Java compiler api - build a jar file from the compiled classes - copy the jar to local file system or hdfs so it can be loaded for a region This addresses bug HBase-3516. https://issues.apache.org/jira/browse/HBase-3516 Diffs ----- src/main/java/org/apache/hadoop/hbase/coprocessor/CoprocessorHost.java 0a1fb2a src/test/java/org/apache/hadoop/hbase/coprocessor/TestClassLoading.java PRE-CREATION Diff: https://reviews.apache.org/r/963/diff Testing ------- Thanks, Mingjie > Coprocessors: add test cases for loading coprocessor jars from hdfs and local > fs. > ---------------------------------------------------------------------------------- > > Key: HBASE-3516 > URL: https://issues.apache.org/jira/browse/HBASE-3516 > Project: HBase > Issue Type: Improvement > Components: coprocessors > Affects Versions: 0.90.0 > Reporter: Mingjie Lai > Assignee: Mingjie Lai > > Loading coprocessors classes from jar files (at hdfs or local fs) is > supported from CP framework right now. We used to have a test case to cover > this scenario which uses an base-64 encoded string at the test case to > represent a compiled jar file. This hardcoded way was not acceptable as a > valid test case, so we removed it eventually. > We need to have a better way to redo this case. Option 1) modify maven file > in order to compile a test cp class into jar, and put it to hdfs and local > fs, and run the cp class loading test; option 2) use Java 6.0 Compiler API to > compile the test case at runtime and create the jar file? > Need more time to investigate which one is better. -- This message is automatically generated by JIRA.
