Chris Li commented on HADOOP-10279: ----------------------------------- Hi [~zhaoyunjiong], thanks for taking a look. This is handled in the FairCallQueue: it treats the index from the Multiplexer as a suggestion and works on the first non-empty queue, starting from this suggestion. So if the Mux suggests queue 2 but queues 2, 3, and 4 are empty, the FairCallQueue will use queue 5, or whatever queue is not empty. This way, the Mux doesn't need to know anything about what queues are. > Create multiplexer, a requirement for the fair queue > ---------------------------------------------------- > > Key: HADOOP-10279 > URL: https://issues.apache.org/jira/browse/HADOOP-10279 > Project: Hadoop Common > Issue Type: Sub-task > Reporter: Chris Li > Attachments: subtask2_add_mux.patch > > -- This message was sent by Atlassian JIRA (v6.2#6252)
