Gergely Novák commented on HDFS-10391:
--------------------------------------
Thank you [~xyao] for your review!
Based on your suggestions in the latest patch (#008) I
- modified the description of dfs.namenode.servicerpc-address in
hdfs-default.xml
- removed the fallback to RPC bind host from NamenodeRpcServer
- introduced globalTimeout in TestDataNodeMetricsLogger
As for your other comments:
- "can we add some test with/wo service rpc/rpc binding host?" I think this is
still properly covered by
TestNameNodeRespectsBindHostKeys.testServiceRpcBindHostKey(). Maybe add one
additional test case there where we don't set the
dfs.namenode.servicerpc-address explicitly?
- I'm not confident about the other two comments regarding the
NamenodeRpcServer. [~arpitagarwal] could you please address them?
