-----------------------------------
Summary: Remove duplicate initializeGenericKeys method when
creating DFSZKFailoverController
Key: HDFS-15546
URL: https://issues.apache.org/jira/browse/HDFS-15546
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: jianghua zhu
When calling the DFSZKFailoverController#create() method, call
NameNode#initializeGenericKeys() twice.
First call:
DFSZKFailoverController#create() {
...
NameNode.initializeGenericKeys(localNNConf, nsId, nnId);
...
}
The second call:
NNHAServiceTarget construction method:
NNHAServiceTarget() {
...
NameNode.initializeGenericKeys(targetConf, nsId, nnId);
...
}
In fact, the parameters passed in the two calls are the same. Here you can
remove the first call without affecting the program itself.
