Kihwal Lee created HADOOP-8611: ---------------------------------- Summary: Allow fall-back to the shell-based implementation when JNI-based users-group mapping fails Key: HADOOP-8611 URL: https://issues.apache.org/jira/browse/HADOOP-8611 Project: Hadoop Common Issue Type: Bug Components: security Affects Versions: 2.0.0-alpha, 0.23.0, 1.0.3 Reporter: Kihwal Lee Assignee: Kihwal Lee Fix For: 1.1.1, 0.23.3, 3.0.0, 2.2.0-alpha
When the JNI-based users-group mapping is enabled, the process/command will fail if the native library, libhadoop.so, cannot be found. This mostly happens at client-side where users may use hadoop programatically. Instead of failing, falling back to the shell-based implementation will be desirable. Depending on how cluster is configured, use of the native netgroup mapping cannot be subsituted by the shell-based default. For this reason, this behavior must be configurable with the default being "disabled". -- This message is automatically generated by JIRA.
