Subject [jira] [Commented] (HDFS-13490) RBF: Fix setSafeMode in the Router
Date Mon, 23 Apr 2018 16:17:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16448376#comment-16448376

Íñigo Goiri commented on HDFS-13490:
------------------------------------

I tried to put it into TestRouterRpc but then we need to create the MiniDFSCluster for every
test which is pretty expensive.
I also tried to make the whole MiniDFSCluster always HA but I was having issues to make it
work.

I updated TestRouterRpc in [^HDFS-13490.001.patch] to test more of the safe mode but it's
not enough as we need the namenodes in HA to trigger the bug.

> RouterRpcServer doesn't handle the isChecked parameter correctly when forwarding setSafeMode
to the namenodes.
