Yiqun Lin commented on HDFS-13655: ---------------------------------- I'm also a little worried about the current JIRA numbers. I take a quick glance of recent RBF JIRAs. There are not only error handling of the Router admin, also have others following: * HDFS-13845:The default MountTableResolver cannot get multi-destination path for the DestinationOrder * HDFS-13841: After Click on another Tab in Router Federation UI page it's not redirecting to new tab * HDFS-13835: RBF: Unable to add files after changing the order * HDFS-13852: RBF: The DN_REPORT_TIME_OUT and DN_REPORT_CACHE_EXPIRE should be configured in RBFConfigKeys. * HDFS-13802: RBF: Remove FSCK from Router Web UI, because fsck is not supported currently For the critical issues, we can directly merge to trunk. For most of others (not critical issues), I prefer to merge these JIRAs in the same branch and make the branch stabilised. So the new branch will focus on: * ClientProtocol APIs implementation to RBF * Router admin error handling improvments * Other improvements(e.g. setting configurable, normal bug fixes) One thing I'm sure, it's not appropriate to directly merge these all to trunk now. > RBF: Add missing ClientProtocol APIs to RBF > ------------------------------------------- > > Key: HDFS-13655 > URL: https://issues.apache.org/jira/browse/HDFS-13655 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Xiao Chen > Priority: Major > > As > [discussed|https://issues.apache.org/jira/browse/HDFS-12858?focusedCommentId=16500975&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16500975|#comment-16500975] > with [~elgoiri], there are some HDFS methods that does not take path as a > parameter.
