------------------------------------
Summary: MiniHadoopClusterManager doesn't respect lack of format
option
Key: HADOOP-14970
URL: https://issues.apache.org/jira/browse/HADOOP-14970
Project: Hadoop Common
Issue Type: Bug
Reporter: Erik Krogen
Assignee: Erik Krogen
Priority: Minor
The CLI MiniCluster, {{MiniHadoopClusterManager}}, says that by default it does
not format its directories, and provides the {{-format}} option to specify that
it should do so. However, it builds its {{MiniDFSCluster}} like:
{code}
dfs = new MiniDFSCluster.Builder(conf).nameNodePort(nnPort)
.nameNodeHttpPort(nnHttpPort).numDataNodes(numDataNodes)
.startupOption(dfsOpts).build();
{code}
{{MiniDFSCluster.Builder}}, by default, sets {{format}} to true, so even though
the {{startupOption}} is {{REGULAR}}, it will still format regardless of
whether or not the flag is supplied.
