Akira Ajisaka created HADOOP-17299: -------------------------------------- Summary: DistCp should fail fast if the configuration is not valid Key: HADOOP-17299 URL: https://issues.apache.org/jira/browse/HADOOP-17299 Project: Hadoop Common Issue Type: Bug Components: tools/distcp Reporter: Akira Ajisaka
If the number of Map task is more than 200 and using dynamic option, DistCp always fails by DynamicInputFormat#validateNumChunksUsing. This failure is after building the src/dst paths, which takes more than 10 minutes if the directory is large (i.e. DistCp fails by configuration error after more than 10 minutes). I think DistCp should validate the configuration before building the src/dst paths and fail if the configuration is not valid. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
