yanbin.zhang updated HDFS-16525:
--------------------------------
Description:
System.err should be used when error occurs in multiple methods in DFSAdmin
class,as follows:
{code:java}
//DFSAdmin#refreshCallQueue
...
try{
proxy.getProxy().refreshCallQueue();
System.out.println("Refresh call queue successful for "
+ proxy.getAddress());
}catch (IOException ioe){
System.out.println("Refresh call queue failed for "
+ proxy.getAddress());
exceptions.add(ioe);
}
...
{code}
The test method closed first in TestDFSAdminWithHA also needs to be
modified,otherwise an error will be reported,similar to the following:
{code:java}
[ERROR] Failures:
[ERROR]
TestDFSAdminWithHA.testRefreshCallQueueNN1DownNN2Up:726->assertOutputMatches:77
Expected output to match 'Refresh call queue failed for.*
Refresh call queue successful for.*
' but err_output was:
Refresh call queue failed for localhost/127.0.0.1:12876
refreshCallQueue: Call From h110/10.1.234.110 to localhost:12876 failed on
connection exception: java.net.ConnectException: Connection refused; For more
details see: http://wiki.apache.org/hadoop/ConnectionRefused and output was:
Refresh call queue successful for localhost/127.0.0.1:12878{code}
