Amir Langer created HDFS-5734: --------------------------------- Summary: A NN-internal RPC BM service Key: HDFS-5734 URL: https://issues.apache.org/jira/browse/HDFS-5734 Project: Hadoop HDFS Issue Type: Sub-task Components: namenode Reporter: Amir Langer
Separate the BM from NN by running it with with its own thread-pool and RPC protocol but still in the same process as NN. NN and BM will in interact through some loopback call that will simulate a separate service. This sprint still assumes a one to one relation between NN and BM and does not split the BM to a separate process, only simulates such a split inside the same VM. This allows us to defer any configuration issue / Testing support / scripts changes to later tasks. This task will therefore also not handle any HA issue to the BM itself. It will, however, deal with having BM code actually running in a different thread to the NN code and will handle building the initialisation / lifecycle code to an independent BM. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
