Erik Steffl commented on HADOOP-6864: ------------------------------------- HADOOP-6884-0.22-1.patch for trunk: - combines HADOOP-6855 0.20 and HADOOP-6884 0.20 patches (i.e. both shell and JNI implementations) - implements suggestion in HADOOP-6878 - has improved test, see instructions in TestAccessControlList - adds support for new API in AccessControlList (addGroup) > Provide a JNI-based implementation of ShellBasedUnixGroupsNetgroupMapping > (implementation of GroupMappingServiceProvider) > ------------------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-6864 > URL: https://issues.apache.org/jira/browse/HADOOP-6864 > Project: Hadoop Common > Issue Type: Improvement > Components: security > Reporter: Erik Steffl > Fix For: 0.22.0 > > Attachments: HADOOP-6864-0.20.1xx-1.patch, > HADOOP-6864-0.20.1xx.patch, HADOOP-6884-0.22-1.patch > > > The netgroups implementation of GroupMappingServiceProvider (see > ShellBasedUnixGroupsNetgroupMapping.java) does a fork of a unix command to > get the netgroups of a user. Since the group resolution happens in the > servers, this might be costly. This jira aims at providing a JNI-based > implementation for GroupMappingServiceProvider. > Note that this is similar to what > https://issues.apache.org/jira/browse/HADOOP-6818 does for implementation of > GroupMappingServiceProvider that supports only unix groups. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
